PSI to Bar Converter
Convert PSI to bar pressure
Frequently Asked Questions
How do I convert PSI to bar?
Divide PSI by 14.5038. 1 PSI = 0.06895 bar. 30 PSI = 2.07 bar. 100 PSI = 6.895 bar. Quick estimate: divide PSI by 14.5. The converter handles PSI, bar, kPa, and atm simultaneously.
What is the correct tire pressure in PSI and bar?
Typical car tires: 30-35 PSI = 2.07-2.41 bar. Bicycle road tires: 80-130 PSI = 5.5-9.0 bar. Mountain bike: 30-50 PSI = 2.1-3.4 bar. Check your vehicle's door sticker for the recommended pressure.
What is the difference between PSI and bar?
PSI (pounds per square inch) is used in the US and UK. Bar is used in most other countries. 1 bar = 14.504 PSI ≈ atmospheric pressure at sea level. 1 atm = 14.696 PSI = 1.01325 bar exactly.
How do I convert PSI to kPa?
Multiply PSI by 6.89476. 1 PSI = 6.895 kPa. 32 PSI = 220.6 kPa. 100 PSI = 689.5 kPa. Canadian tire pressure is often listed in kPa. 1 bar = 100 kPa exactly.
What PSI is dangerous for tires?
Most car tires have a maximum rating of 44-51 PSI (3.0-3.5 bar) stamped on the sidewall. Exceeding this causes blowout risk. Under-inflation below 25 PSI (1.7 bar) causes poor handling and increased wear. Check pressure when tires are cold.
