What is 1 PSI in bar?

1 PSI equals 0.069 bar, or 6.9 kPa. Multiply PSI by 0.0689476 to convert.

How do I convert 1 PSI to bar without a calculator?

Divide by 14.5 for a quick estimate: 1 ÷ 14.5 ≈ 0.07 bar. The exact answer is 0.069 bar.

1 PSI may be outside typical passenger-car range (30–35 PSI). Consult your vehicle's door-jamb sticker.

1 PSI = 6.9 kPa. Tire pressures in Canada and Europe are often given in kPa.
