How to convert PSI to BAR
PSI (pounds per square inch) and bar are both units of pressure. The conversion between them is fixed: 1 bar = 14.5038 PSI, or equivalently 1 PSI = 0.0689476 bar. To convert PSI to bar, multiply by 0.0689476. This calculation runs instantly in your browser as pure JavaScript arithmetic. Bar is the preferred unit in most of the world for tire pressure, gas pressure, and industrial applications; PSI is standard in the US.
The most practical everyday use of this conversion is tire pressure. A car tire inflated to 35 PSI equals approximately 2.41 bar. A mountain bike tire at 30 PSI is about 2.07 bar. European tire pressure gauges often read in bar; North American ones in PSI. Transferring between the two systems is necessary when reading pressure specs from one country and using tools calibrated to the other.
Enter the pressure in PSI
Type the PSI value. Decimals are accepted (e.g., 32.5 PSI for a tire pressure reading).
Read the bar result
The result appears instantly: PSI x 0.0689476. Default precision is 2-3 decimal places.
Also see kPa
Kilopascals (kPa) are also shown since some pressure gauges use kPa. 1 bar = 100 kPa exactly.
Reverse if needed
Enter bar to get PSI: multiply bar by 14.5038.
Frequently asked questions
What is the conversion factor from PSI to bar?
1 PSI = 0.0689476 bar exactly. Alternatively, 1 bar = 14.5038 PSI.
What is standard tire pressure in bar?
Most car tires are inflated to 2.0-2.5 bar (29-36 PSI). Check your vehicle's door placard or owner's manual for the manufacturer's recommendation.
What is atmospheric pressure in PSI and bar?
Standard atmosphere (atm) = 14.696 PSI = 1.01325 bar. This is the pressure at sea level.
Is bar the same as atmosphere (atm)?
Very close but not identical. 1 bar = 0.9869 atm. For most practical purposes (tire pressure, industrial gauges) they are used interchangeably, but scientifically they are different.
What is gauge pressure vs absolute pressure?
Gauge pressure is measured relative to atmospheric pressure (so 0 psi gauge = 1 atm absolute). Absolute pressure includes atmospheric pressure. Tire pressure specifications use gauge pressure.
