Pressure Converter
PSI (lb/in²)
A PSI to bar converter converts pressure between the imperial unit pounds per square inch (PSI) and the metric unit bar. Used for tyre pressure, hydraulic systems, and industrial equipment.
- 11 bar = 14.5038 PSI
- 21 PSI = 0.0689476 bar
- 3Bar = PSI × 0.0689476
- 4Standard atmospheric pressure = 14.696 PSI = 1.01325 bar
35 PSI (car tyre)=2.41 bar
100 PSI (bicycle tyre)=6.89 bar
3 bar (recommended tyre)=43.5 PSI
| PSI | Bar | Application |
|---|---|---|
| 14.7 | 1.01 | Atmospheric pressure |
| 30 | 2.07 | Car tyre (low) |
| 35 | 2.41 | Car tyre (typical) |
| 45 | 3.10 | Van tyre |
| 80 | 5.52 | Road bike |
| 120 | 8.27 | Racing bicycle |
