Pressure Converter
Bar
A bar to PSI converter converts metric pressure (bar) to the imperial unit pounds per square inch. Bar is the standard pressure unit in most of the world for weather, tyres, and industrial equipment.
- 11 bar = 14.5038 PSI
- 21 PSI = 0.068948 bar
- 3PSI = Bar × 14.5038
- 41 millibar = 0.0145 PSI (used in weather)
2.5 bar (car tyre)=36.26 PSI
1.013 bar (atmospheric)=14.70 PSI
8 bar (road bike)=116.03 PSI
| Bar | PSI | Application |
|---|---|---|
| 1 | 14.50 | Atmospheric ~1 bar |
| 2 | 29.01 | Low tyre pressure |
| 2.5 | 36.26 | Car tyre typical |
| 3 | 43.51 | Higher pressure tyre |
| 6 | 87.02 | Bicycle road tyre |
| 10 | 145.04 | Industrial hydraulic |
