Unit Converters
Pressure Converter
Pressure Converter switches a pressure reading between pascals, kilopascals, bar, PSI, atmospheres and millimetres of mercury (mmHg).
Handy for tyre pressure, weather readings, engineering specs and lab measurements that use different regional units.
How to Use the Pressure Converter
- Open the Pressure Converter tool.
- Enter the pressure value you want to convert.
- Choose the unit you're converting from.
- Choose the unit you want to convert to.
- Read the converted result, updated instantly.
Frequently Asked Questions
What unit is tyre pressure usually measured in?
Most regions use PSI or bar for tyre pressure; some vehicle manuals list kPa as well. This tool converts between all of them.
What's the difference between 1 atm and 1 bar?
1 atmosphere (atm) is approximately 1.01325 bar -- close, but not identical, so precise engineering work should always double-check which one a spec uses.
Does this tool store what I type?
No. Everything is calculated locally in your browser and never saved or transmitted.
