Worked Example: Default Pressure (PSI ↔ Bar ↔ kPa) Scenario
Convert gauge and absolute fluid/tire pressure across Pounds per Square Inch (PSI), Bar, Kilopascals (kPa), Megapascals (MPa), Standard Atmospheres (atm), and mmHg (Torr).
- Enter parameters for Pressure (PSI ↔ Bar ↔ kPa) in the input controls.
- Apply formula: 1 Bar = 100 kPa = 14.5037738 PSI = 0.986923 atm = 750.0617 mmHg.
- Inspect the 3 interactive SVG charts and comparison table for sensitivity across input ranges.
Result: Produces instant Pressure (PSI ↔ Bar ↔ kPa) output with domain-verified units and sensitivity table.

Pressure Unit Converter (PSI, Bar, kPa, MPa, Atm & Torr/mmHg): inputs, method, and how to read the result
Convert PSI, Bar, kPa, MPa, atm, and mmHg/Torr for tires, hydraulics, and vacuum systems.
Choose inputs for the case you are checking
The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.
- Pressure In Psi: Input pressure in Pounds per Square Inch (PSI).
- Atmospheric Baseline Psi: Local ambient atmospheric pressure (14.696 psia at sea level) for PSIG → PSIA.
What the calculation includes
With the default values shown, Pressure in Bar & kPa is 2.413 bar (241.3 kPa). The calculation follows Pressure (PSI ↔ Bar ↔ kPa) Formula; the formula and variable definitions above show how the inputs combine.
One-input check: With the other defaults held constant, changing Pressure In Psi from 35 PSI to 39 PSI changes Pressure in Bar & kPa from 2.413 bar (241.3 kPa) to 2.689 bar (268.9 kPa). This is a comparison inside the calculator's stated model, not a prediction.
Where to use caution
- Inputs are within standard operating ranges for the specified equation.
- Extreme boundary conditions may require specialized empirical adjustments.
Scope: Global Standard Check the assumptions and limitations against your situation before relying on the estimate.
