About Pressure Converter
Pressure represents force applied perpendicular to the surface of an object per unit area (P = F / A).
Key physical standards: • 1 Atmosphere (atm) = 101,325 Pascals = 1.01325 bar = 14.6959 psi = 760 mmHg. • 1 Bar = 100,000 Pascals (100 kPa) ≈ 14.5038 psi.
How to use Pressure Converter
- Type the value you want to convert.
- Choose the unit you are converting from and the unit you want, such as pascals, bar, psi, atmospheres or mmHg.
- Read the converted value instantly. Swap the units to convert the other way.
- Copy the result, or check other units listed in the results grid.
Worked examples
Input: 32 psi to kilopascals
Result: About 220.63 kPa, or 2.206 bar.
Input: 1 atm to hectopascals
Result: 1,013.25 hPa.
Background
Pressure is force per area, measured in pascals (N/m2). One bar is 100,000 Pa, one atmosphere is 101,325 Pa, one psi is about 6,894.757 Pa and one mmHg is about 133.322 Pa.
Tire gauges usually read psi or bar, weather reports use hPa, and medical blood-pressure readings use mmHg.
Common mistakes
- Mixing gauge pressure with absolute pressure. A tire gauge reads pressure above atmospheric.
- Confusing bar with atm. They differ by about 1.3%.
- Reading mmHg and Torr as always interchangeable for precise work.
