What the Pressure Converter does
This tool converts between pressure units used in tires, weather, diving, engineering, and lab work. It handles pascals and kilopascals, bar, psi, atmospheres, millimeters of mercury, and Torr, so you can move between a tire spec in psi and a gauge in bar, or a weather reading in hPa-style kPa and mmHg, in one step.
How to use it
- Type the figure in the Value box.
- Set From to your current unit (for example bar).
- Set To to the unit you want (for example psi).
- Press Convert to read the result below.
Handy anchors
A few reference points: standard atmosphere is about 101.3 kPa, 1 bar is very close to 1 atm, and tire pressures are often given in both bar and psi. The factors here are precise, and because the math runs entirely in your browser, nothing you enter is sent or stored on a server.
Frequently asked questions
- Which pressure units does it support?
- Pascal, kilopascal, bar, psi, atmosphere (atm), millimeters of mercury (mmHg), and Torr. Any pair works, like bar to psi or kPa to psi.
- How do I convert bar to psi?
- Enter the value, set From to bar and To to psi, then press Convert. As a rough guide, 1 bar is about 14.5 psi.
- Is anything uploaded?
- No. The conversion runs in your browser, so your numbers never leave your device. No account, no limits.
