Bar to Psi Converter
How to convert bar to psi
psi = bar × 14.5037738
To convert bar to psi, multiply the number of bar by 14.5037738.
1 bar = 14.5037738 psi
Examples
- A typical car tire pressure: 2.2 bar × 14.5037738 = 31.9083023 psi
- 1 bar × 14.5037738 = 14.5037738 psi
Good to know
One bar is about 14.5 psi, so 2.2 bar is roughly 32 psi. Tire pressures are given in bar in most of Europe and in psi in the United States and United Kingdom.
Psi means pounds-force per square inch (lbf/in²). Gauge readings (psig) are measured relative to atmospheric pressure, absolute readings (psia) relative to a vacuum; the conversion factor is the same for both.

Unit definitions
- Bar
- A bar is exactly 100,000 pascals, slightly less than average atmospheric pressure at sea level. It is widely used in Europe for tire pressures, weather and industrial equipment.
- Psi
- Psi is one pound-force per square inch, about 6894.757 pascals. It is the everyday pressure unit in the United States, used for tires, compressors and plumbing.
