Metrology toolbox · pressure

Pressure values need a reference.

Relate gauge and absolute pressure using the actual atmospheric input, then calculate hydrostatic pressure or liquid head with density and gravity exposed.

Gauge and absolute reference

Convert between pressure references using an explicit atmospheric value rather than an invisible standard-atmosphere assumption.

Hydrostatic relationship

Pressure and liquid head

Use ΔP = ρgh for a static, constant-density fluid.

Pressure-unit conversion remains in the Unit Converter. This workspace adds pressure-reference and hydrostatic context.
