Pressure Converter accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

All units are converted relative to Pascals (Pa), the SI unit of pressure. * **1 Bar** = 100,000 Pa = 14.5038 PSI * **1 ATM** = 101,325 Pa = 14.696 PSI * **1 PSI** = 6,894.76 Pa

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

Pressure: 30
From: PSI
To: Bar

Expected outputs

Converted Value: 2.07
Logic: 1 psi ≈ 0.06895 bar

Known limitations

This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

Values are converted as scalar pressure magnitudes using standard reference factors relative to pascals.
The tool does not distinguish between gauge, absolute, or differential pressure unless your source value already does.
Displayed results do not account for temperature, altitude, or fluid-state changes that can matter in real systems.

Unit handling

Pressure accepts numeric values.
From accepts one of the configured options.
To accepts one of the configured options.

Rounding rules

Number displays use up to 2 decimal places in the calculator UI.
