Unit converter Convert one engineering quantity at a time while retaining the entered value, source unit, destination unit, and displayed precision.
Open feature What you need Quantity category Source value and unit Destination unit Display precision Step by step Choose the physical quantity before entering the number. Enter the source value exactly as known; do not pre-round it. Select the source and destination units. Choose display precision appropriate to the source resolution. Use Swap when checking the reverse conversion. How to read the result The large result is the converted value, not a statement of measurement accuracy. Scientific notation is appropriate for very large or small results. A displayed trailing zero reflects formatting, not additional supported resolution. Worked example Select Length, enter 1 in, and convert to mm. The result is 25.4 mm.
Important limits Confirm conventional-unit definitions and reference conditions where they matter. Do not report more meaningful digits than the source measurement supports. Back to Help index ↑ 02 Free toolbox
Conductivity and resistivity Calculate reciprocal conductivity/resistivity, conductivity from a calibrated cell constant, and temperature-normalized values.
Open feature What you need Conductivity or resistivity value and unit For cell measurements: resistance and calibrated cell constant For compensation: measurement temperature, reference temperature, and validated coefficient Step by step Choose Reciprocal, Cell measurement, or Temperature compensation. Enter the source value and its unit. For a cell calculation, copy the cell constant and unit from the applicable calibration record. For compensation, enter the method-approved reference temperature and coefficient. Review both SI and common laboratory-unit results. How to read the result Conductivity and resistivity are reciprocal properties only when the quantities and units describe the same material state. Cell mode uses conductivity = cell constant ÷ resistance. The temperature result is model-dependent, not a universal correction. Worked example A 1 MΩ measurement with a 1 cm⁻¹ cell constant produces 1 µS/cm.
Important limits Use a validated compensation model for the sample or standard. Account for electrode polarization, geometry, frequency and temperature when required. Back to Help index ↑ 03 Free toolbox
4–20 mA scaling Move between loop current, percent span and engineering units while displaying common NAMUR-style diagnostic regions.
Open feature What you need Lower and upper range values Engineering unit Current, percent span, or engineering-value input Step by step Enter the transmitter lower range value (LRV) and upper range value (URV). Name the engineering unit. Choose which quantity you already know. Enter the source value. Review the equivalent current, percent span, engineering value and diagnostic label. How to read the result 4 mA corresponds to 0% and 20 mA to 100% for a normal linear range. Values outside 4–20 mA may still be intentional diagnostic signals. The diagnostic badge is decision support; instrument configuration controls. Worked example For a 0–100 °C range, 12 mA corresponds to 50% span and 50 °C.
Important limits Verify live-zero, square-root extraction, custom transfer functions and configured alarm limits. De-energize and follow electrical safety procedures before loop work. Back to Help index ↑ 04 Free toolbox
TUR, TAR, guardbanding and tolerance Calculate ratios, guardbanded acceptance limits, conformity classifications and asymmetric numerical tolerance checks.
Open feature What you need Measured value and applicable limits Expanded uncertainty U and optional reference standard specification Decision-rule method and custom multiplier when used For tolerance screening: nominal and asymmetric allowances Step by step Choose two-sided, upper-only or lower-only limits. Enter the measured value and limits in the same unit. Enter expanded uncertainty, including the coverage basis used by the procedure. Choose simple acceptance, guard band by U, or a controlled custom multiplier. Review acceptance limits, TUR/TAR and the four-state classification. How to read the result Pass means the result lies inside the selected acceptance interval. Conditional pass/fail identifies transition regions; your approved decision rule determines the reportable statement. For two-sided specifications, TUR = total tolerance width ÷ 2U. Worked example Limits 99–101 with U = 0.25 produce TUR 4:1. Guard band by U creates acceptance limits 99.25–100.75.
Important limits Agree the decision rule before measurement when required. This tool does not calculate consumer or producer risk probabilities. Back to Help index ↑ 05 Free toolbox
Statistics and tolerance stacks Summarize repeated measurements and compare worst-case with root-sum-square tolerance accumulation.
Open feature What you need At least two repeated measurements For stacks: component nominals and bilateral tolerances Step by step Paste or type measurements separated by commas, spaces, semicolons or new lines. Review mean, median, range, sample standard deviation, standard error and 95% interval. Use standard error as Type A standard uncertainty only when the sampling model supports it. For a stack, add every contributing dimension with its sign already represented in the nominal. Compare worst-case and RSS results. How to read the result Sample standard deviation describes observed dispersion; standard error describes uncertainty of the estimated mean. Worst-case adds tolerance magnitudes. RSS is a statistical estimate and is usually smaller than worst-case. Worked example For 1, 2, 3, 4, 5, the mean is 3 and sample standard deviation is approximately 1.5811.
Important limits Investigate independence, stability, resolution, outliers and distribution before formal use. RSS requires a justified statistical model and does not replace design validation. Back to Help index ↑ 06 Free toolbox
Electrical tools Solve DC Ohm’s-law/power relationships, combine resistor networks and normalize resistance for temperature.
Open feature What you need A selected pair of voltage, current, resistance or power Resistor values for series/parallel networks Measured resistance, temperatures and validated temperature coefficient Step by step Choose the known-quantity pair and enter both non-negative values. Review all four equivalent electrical quantities. For a network, list resistor values and compare series with parallel equivalents. For temperature normalization, enter measurement and reference temperatures plus the material coefficient. How to read the result The solver assumes steady DC relationships and ideal components. A zero-ohm parallel branch makes the parallel equivalent zero. Temperature normalization is a first-order linear approximation. Worked example 12 V and 2 A produce 6 Ω and 24 W.
Important limits Do not apply DC formulas directly to reactive AC circuits. Use component-specific temperature coefficients and safety ratings. Back to Help index ↑ 07 Free toolbox
Temperature corrections Calculate indication error, apply a two-point linear correction, and normalize dimensional measurements to a reference temperature.
Open feature What you need Indicated and reference temperature Two indicated/reference calibration pairs Measured length, temperatures and linear expansion coefficient Step by step Choose Error, Two-point correction, or Length at reference temperature. Enter values in the labeled fields without changing signs. For two-point correction, confirm the low and high indicated points differ. For length correction, use the applicable material coefficient in µm/(m·°C). Treat extrapolation warnings as a review condition. How to read the result Error = indicated − reference; correction has the opposite sign. Two-point mode fits a straight line through the entered calibration pairs. Length mode applies a first-order thermal expansion correction. Worked example An indication of 100.2 °C against 100.0 °C has +0.2 °C error and −0.2 °C correction.
Important limits Account for immersion, stem conduction, self-heating, response and stability as applicable. Do not extrapolate a calibration model without technical justification. Back to Help index ↑ 08 Free toolbox
Pressure tools Convert pressure units, move between gauge and absolute reference, and calculate hydrostatic pressure or liquid head.
Open feature What you need Pressure value and units Atmospheric pressure for gauge/absolute conversion Fluid density, height/pressure and gravity for hydrostatic work Step by step Choose Conversion, Gauge/absolute, or Hydrostatic. Keep pressure and atmospheric reference in the same unit. For hydrostatic work, enter density at the applicable conditions. Use local gravity when your method requires it; otherwise standard gravity is shown. Review the scope note for conventional liquid-column units. How to read the result Absolute pressure = gauge pressure + atmospheric pressure. Hydrostatic differential pressure uses ΔP = ρgh. Negative gauge pressure can represent pressure below the entered atmosphere. Worked example 1 psi converts to approximately 6.894757 kPa.
Important limits Reference conditions affect mmHg, inHg and inH₂O realizations. The hydrostatic model assumes a static, uniform-density column. Back to Help index ↑ 09 Free toolbox
GD&T true position and material condition Screen a single cylindrical feature using true position, MMC/MMR departure, bonus tolerance and virtual condition.
Open feature What you need ASME or ISO terminology mode Internal or external feature and material modifier Lower, upper and actual feature size Stated diametrical position tolerance Basic and actual X/Y coordinates Step by step Choose the terminology set used by the drawing. Identify whether the feature is internal or external. Enter size limits, actual size and the stated position tolerance. Enter basic and actual coordinates in the same unit. Review size and position status separately before the combined status. How to read the result Diametrical true position is twice the radial coordinate deviation. At MMC/MMR, favorable departure may create bonus tolerance. Virtual condition is reported only for the supported maximum-material case. Worked example Basic (1,2), actual (1.1,2.1) gives diametrical true position 0.2828427. A 10.1 hole with 10.0 MMC and 0.2 stated tolerance has 0.1 bonus and 0.3 available tolerance.
Important limits Not included: datum mobility, composite position, patterns, projected zones, envelope evaluation, form error, sampling or uncertainty. ASME and ISO modes are terminology aids; the drawing and licensed standard control. Back to Help index ↑ 10 Account & delivery
Sign in, install and synchronize Use the same Kanonix account on the website and iOS app, preserve the session, and install the website as a PWA when desired.
Open feature What you need Your account email or configured Google account Access to the sign-in email when using a magic link Kanonix Pro entitlement for cloud workspace features Step by step Select Account and choose an available sign-in method. Complete the email link or Google flow in the same browser/device. Confirm the account page shows the expected email and plan. On iOS, sign in with that same email in Settings. Use Synchronize Records only after confirming the account and plan. How to read the result Free identifies an authenticated account without an active Pro entitlement. Pro access follows the shared account rather than one device. The install control adds the PWA; it does not create a second account. Worked example Signing in on the website and iOS with the same email exposes the same Pro entitlement.
Important limits Do not forward sign-in links. If a link opens the wrong browser, return to the original device and start a fresh sign-in. Back to Help index ↑ 11 Kanonix Pro
Uncertainty budgets Build, save and review independent-input uncertainty budgets with distributions, sensitivity coefficients and expanded uncertainty.
Open feature What you need Measurand and unit Type A and Type B components Component magnitude, distribution/divisor, sensitivity coefficient and degrees of freedom Coverage factor Step by step Name the budget and define the measurand/unit. Add each significant uncertainty component once. Choose whether the entry is already standard uncertainty or requires a distribution divisor. Enter the signed sensitivity coefficient and finite degrees of freedom where applicable. Review variance contributions, combined standard uncertainty, effective degrees of freedom and expanded uncertainty. Sign in to save the budget. How to read the result The engine combines independent contributions by root-sum-square. Contribution percentage is based on variance, not the raw component magnitude. Expanded uncertainty U = k × combined standard uncertainty. Worked example Repeatability 0.2 standard, resolution 0.6 digital and certificate 0.4 with divisor 2 produce combined standard uncertainty about 0.3316625 and U about 0.663325 at k = 2.
Important limits Correlated inputs require covariance terms and are outside the current model. The analyst remains responsible for completeness, distribution choice, sensitivity coefficients and reporting. Back to Help index ↑ 12 Kanonix Pro
Equipment library, imports and calibration history Create controlled equipment records, import CSV data, preserve calibration history, and monitor due status.
Open feature What you need Unique Equipment ID / Asset ID Description, manufacturer, model, serial number and location Calibration interval and last/next dates CSV prepared from the provided column rules Step by step Create a record manually or open Import Equipment. For CSV, review the mapping and validation preview before committing. Resolve duplicate Equipment IDs / Asset IDs and invalid dates. Open an asset to add calibration history and update the next due date. Use search and status filters to find due-soon or overdue assets. Use the import rollback option only for the identified batch. How to read the result Due status is derived from the stored next calibration due date. Calibration history is distinct from the current equipment master fields. Import previews do not change records until confirmed. Worked example A 12-month interval and last calibration on 2026-08-01 produces a planned next date around 2027-08-01, subject to the approved interval procedure.
Important limits Equipment IDs / Asset IDs must remain stable and unique. Verify imported records and date semantics before using them for compliance scheduling. Back to Help index ↑ 13 Kanonix Pro
Calibration interval analysis Use calibration history and controlled decision settings to recommend extending, retaining or reducing an interval.
Open feature What you need Current/minimum/maximum interval Extension and reduction percentages Guardband and extension thresholds Required consecutive in-tolerance calibrations Ordered calibration history with as-found results Step by step Select or define the equipment and current interval. Set organizational control limits before evaluating history. Enter post-adjustment/as-found outcomes consistently. Review the calculated recommendation, limiting condition and next interval. Save the analysis to the shared account when approved. How to read the result A recommendation is decision support, not an automatic master-data change. OOT or high tolerance utilization normally drives retention or reduction. Extension requires sufficient controlled passing history. Worked example Three qualifying passes below the extension threshold may support a controlled extension, capped by the entered maximum interval.
Important limits Apply the approved interval program, risk classification and regulatory commitments. Do not omit intervening failures, adjustments or service events. Back to Help index ↑ 14 Kanonix Pro
OOT and drift investigations Quantify observed error and drift, forecast tolerance risk, and preserve an investigation record with impact and disposition notes.
Open feature What you need Equipment and test point Prior and current dates/results Applicable tolerance or limits Impact assessment, disposition and notes Step by step Select the affected asset and identify the test point/unit. Enter ordered prior and current results with dates. Confirm the tolerance basis and sign convention. Review drift amount, rate and projected threshold timing. Document product/process impact and the controlled disposition. Save the investigation and update it as evidence develops. How to read the result Drift is the change between entered results; rate depends on elapsed time. A forecast assumes the observed trend continues and is not a guarantee. OOT classification and impact are quality-system decisions. Worked example A change from 0.10 to 0.25 over 12 months represents +0.15 units/year under a linear model.
Important limits Two points do not establish a stable trend. Include uncertainty, adjustments, environmental changes, repairs and intermediate checks in the investigation. Back to Help index ↑ 15 Account & delivery

Complete checkout and return to Kanonix. Open Account and refresh status if the plan does not update immediately. Use Manage billing for invoices, payment methods, cancellation or renewal details. How to read the result An active entitlement unlocks Pro workspaces on both website and iOS for the same account. Cancellation and access end dates follow the status shown in the billing portal. Worked example After checkout, Account should show Pro and the current subscription status.
Important limits Never send payment information through Contact or email. Billing changes may take a short time to propagate; refresh status before repeating checkout. Back to Help index ↑ 16 Account & delivery
One-time services and deliverables Purchase a defined professional service and retrieve completed deliverables from the account workspace.
Open feature What you need Signed-in account Selected service scope Requested source documents and technical context Step by step Review the service description, included deliverables and exclusions. Sign in and complete checkout. Provide the requested source context without including unnecessary sensitive data. Monitor Purchases and Deliverables in Account. Download the completed file from the deliverable record and preserve it according to your document-control process. How to read the result Purchase status and delivery status are separate. A completed deliverable remains associated with the purchasing account. Worked example After purchasing a report service, the finished report appears under Account → Purchases and Deliverables rather than at the bottom of the shopping page.
Important limits Service output requires customer review and approval before regulated use. Do not upload controlled or confidential data beyond the agreed scope. Back to Help index ↑ 17 Account & delivery
Export or delete account data Use the account controls to obtain a copy of stored data or request deletion through the authenticated workflow.
Open feature What you need Authenticated account and any required confirmation Step by step Open Account and locate Data controls. Choose Export to prepare/download the available account data. Review the export before relying on it as a backup. For deletion, read the consequences and confirm only when you intend to remove the account. Retain required business or quality records elsewhere before deletion. How to read the result Export creates a portable copy; it does not delete cloud records. Account deletion is a separate destructive action and may be subject to required transaction-record retention. Worked example Use Export before closing an account to preserve equipment and calculation records available in the export package.
Important limits Exports are not automatically a validated archival format. Deletion cannot replace your organization’s controlled record-retention process. Back to Help index ↑
