PSI to Bar
1 psi = 0.0689476 bar
To convert psi to bar: bar = psi × 0.0689476
| psi | bar |
|---|---|
| 10 psi | 0.6895 bar |
| 14.7 psi | 1.014 bar |
| 20 psi | 1.379 bar |
| 25 psi | 1.724 bar |
| 28 psi | 1.931 bar |
| 30 psi | 2.068 bar |
| 32 psi | 2.206 bar |
| 35 psi | 2.413 bar |
One psi (pound-force per square inch) is 6,894.76 pascals, and one bar is 100,000 pascals, so multiply psi by 0.0689476 to get bar.

Good to know
Car tires are typically inflated to around 30–35 psi (2.1–2.4 bar), but the right figure is the one on your vehicle's door-jamb placard, not the maximum on the tire sidewall.
Gauge versus absolute: tire gauges read pressure above atmospheric. Atmospheric pressure at sea level is about 14.7 psi or 1.013 bar.
