About the Pressure Converter
The pressure converter changes values between pascals, kilopascals, bar, PSI and standard atmospheres. It converts through the pascal using exact definitions: 1 bar is 100,000 Pa and 1 atm is 101,325 Pa. Tyre pressure is usually quoted in PSI or bar, weather in kilopascals or millibars, and engineering data in pascals or megapascals.
How to use it
- 1Type the value you want to convert.
- 2Choose the unit you are converting from and the unit you want (for example PSI to bar).
- 3The result updates as you type; use the swap button to reverse the direction.
- 4Copy or share the result with the buttons below it.
Worked example
a tyre at 32 PSI is 32 × 6.894757 ≈ 220.6 kPa, or about 2.21 bar. One standard atmosphere is 14.696 PSI.
