PSI to Bar
Convert pound-force per square inch to bar. One PSI is 6894.757293168 Pa. One bar is 100000 Pa. This is the reverse of bar to PSI and does not add atmosphere.

How to convert PSI to bar
- Enter the pressure in PSI. The default is 1.
- Keep From as PSI and To as Bar, or pick kilopascals if a placard uses kPa.
- Read bar. Multiply PSI by 6894.757293168 / 100000.
- Swap units to convert bar back to PSI, or open bar to PSI.
Pound-force per square inch
Pressure (pascal)
| PSI | 1 psi = 6894.757293168 Pa |
|---|---|
| Bar | 1 bar = 100000 Pa |
| Kilopascal | 1 kPa = 1000 Pa, common on vehicle placards |
| Standard atmosphere | 1 atm = 14.6959 PSI approximately |
| Reverse spoke | Bar to PSI uses the same pascal table |
| Gauge | No automatic +1 atm |
What PSI to bar does
This spoke starts at PSI and targets bar, the reverse of bar to PSI. US compressor and tire stickers quote PSI. European sheets quote bar. The factors still run through pascals: 6894.757293168 Pa per PSI and 100000 Pa per bar. One PSI is about 0.0689476 bar.
The pressure hub is pressure. Other dimensions sit on the unit converter.
PSI to bar factor
bar = psi × 6894.757293168 / 100000. psi = bar × 100000 / 6894.757293168. kPa = psi × 6.894757293168. The page treats the number as the same kind of pressure on both sides.
PSI, kPa, and tire placards
Many cars print both kPa and PSI on the door jamb. Bar is 100 kPa. Converting 32 PSI to bar is not the same as converting 32 PSI to kPa. Pick the To unit you need. Torr remains for vacuum lab work on this list.
When to convert PSI to bar here
Turn a 30 PSI spec into bar, check a US compressor against a bar gauge, or switch To to kilopascals. Leave live weather and QNH off this form.
What this page does not do
It does not add 14.7 PSI. It does not read a sensor. It is not a weather product. Input stays in this tab.
