About the Pressure Converter
Tyre gauges, compressors, water pumps and weather reports often use different pressure units. Convert between PSI, bar, kPa, pascal, standard atmospheres and millimetres of mercury (mmHg) in one step.
How to use the Pressure Converter
- Enter a pressure value.
- Choose the units to convert from and to.
- Read the result and the quick table.
How it works
Every unit is converted through pascals (Pa):
- 1 kPa = 1,000 Pa
- 1 bar = 100,000 Pa
- 1 PSI = 6,894.757 Pa
- 1 atm = 101,325 Pa
- 1 mmHg = 133.322 Pa
Examples
- A car tyre at 32 PSI = 2.206 bar = 220.6 kPa.
- 1 atm = 14.696 PSI = 1.01325 bar.
Frequently asked questions
Is a tyre pressure reading absolute or gauge pressure?
Tyre gauges show gauge pressure — the pressure above the surrounding air. The conversion between units is the same either way.
Can I convert to other units too?
Yes. Choose any unit in the From and To lists, or use the main Unit Converter for length, weight, temperature and more.
