Free metrology toolbox
Useful before sign-in. Rigorous after the first number.
Fast calculators for bench work, planning, and technical review. Each tool keeps units, method limits, and reference sources close to the result.
Unit converter
Length, temperature, pressure, mass, force, torque, volume, flow, and electrical units.
Open calculatorConductivity & resistivity
Reciprocal properties, cell constant, resistance, and temperature compensation.
Open calculator4–20 mA scaling
Loop current, percent span, engineering units, and visible diagnostic regions.
Open calculatorDecision tools
TUR, TAR, guardbanding, conformity classification, and asymmetric tolerance checks.
Open calculatorStatistics & tolerance stack
Repeatability, Type A uncertainty, 95% mean intervals, worst-case stacks, and RSS estimates.
Open calculatorElectrical tools
Ohm’s law, DC power, resistor networks, and resistance temperature normalization.
Open calculatorTemperature corrections
Error and correction signs, two-point interpolation, and dimensional correction to reference temperature.
Open calculatorPressure tools
Gauge and absolute pressure references plus hydrostatic pressure and liquid head.
Open calculatorGD&T position tools
True position, MMC and LMC size, bonus tolerance, virtual condition, and requirement screening.
Open calculatorNeed records, not just answers?
Carry the result into Kanonix Pro.
Build uncertainty budgets, monitor intervals, manage equipment, document out-of-tolerance events, and generate traceable deliverables.
