PSI to Bar Converter
Convert between PSI, bar, kilopascal (kPa), megapascal (MPa), atmospheres and kgf/cm². One bar equals 14.5038 PSI — useful for tire pressures, air compressors, hydraulics and pressure gauges.
Common pressure references
| Reference | PSI | Bar | kPa |
|---|---|---|---|
| Standard atmosphere | 14.70 | 1.013 | 101.3 |
| Typical car tire | 32–35 | 2.2–2.4 | 220–240 |
| Road bike tire | 80–120 | 5.5–8.3 | 550–830 |
| Home air compressor | 90–150 | 6.2–10.3 | 620–1,030 |
Frequently asked questions
How many PSI is 1 bar?
One bar equals 14.5038 PSI. To convert bar to PSI, multiply by 14.5038; to convert PSI to bar, divide by 14.5038 (or multiply by 0.06895).
What is a normal car tire pressure in bar?
Most passenger cars specify 2.2–2.4 bar (32–35 PSI) cold. Always check the sticker inside the driver's door jamb — not the maximum printed on the tire sidewall.
Is kPa the same as bar?
They are related: 1 bar = 100 kPa exactly. Tire placards in many countries list pressure in kPa (e.g. 220 kPa = 2.2 bar ≈ 32 PSI).
