About Pressure Converter Tool
Published: Last Updated:
This Pressure Converter converts between PSI (pounds per square inch), bar, Pascal (Pa), kilopascal (kPa), megapascal (MPa), standard atmospheres (atm), torr, and mmHg. Useful for engineering, physics, meteorology, and tyre pressure checks.
Key Features
- Converts PSI, bar, Pa, kPa, MPa, atm, torr, mmHg.
- Real-time conversion.
- Runs in your browser.
How to Use the Tool
- Enter a pressure value.
- Select the input unit.
- All equivalent values appear instantly.
Core Benefits
- Tyre pressure: convert bar (European gauge) to PSI (US gauge).
- Weather: convert meteorological pressure between hPa and mbar.
- Engineering: convert hydraulic system pressures between psi and bar.
Common Use Cases
- Converting European tyre pressure recommendation (2.4 bar) to PSI (34.8 psi).
- Converting weather pressure data from hPa to atm.
- Industrial hydraulics: converting system pressure from bar to MPa.
Pro Tips
- Standard atmospheric pressure = 1 atm = 101.325 kPa = 14.696 psi = 1.01325 bar.
- Tyre pressures: typical car tyre 30–35 psi = 2.07–2.41 bar.
- 1 hPa (hectopascal) = 1 mbar. Meteorology uses hPa for atmospheric pressure.
