Quick Answer:
1 bar = 14.5038 PSI. To convert bar to PSI, multiply the bar value by 14.5038.
Bar and PSI are the primary pressure units for tires, hydraulics, and weather.
Detailed Overview: Bar to PSI
A bar is a metric pressure unit equal to 100,000 pascals. PSI (pounds per square inch) is an imperial pressure unit. 1 bar = 14.5038 PSI. 1 PSI = 0.0689476 bar. Multiply bar by 14.5038 for PSI. Multiply PSI by 0.0689476 for bar. Used in tire pressure, scuba tanks, and hydraulic systems.
Conversion Reference Table
1 bar = 14.5038 PSI, 2 bar = 29.0075 PSI, 2.5 bar = 36.2594 PSI, 3 bar = 43.5113 PSI, 5 bar = 72.5189 PSI, 10 bar = 145.0377 PSI
Practical Calculation Example
Convert 2.2 bar: PSI = 2.2 × 14.5038 = 31.91 PSI. Reverse: 40 PSI = 40 × 0.0689476 = 2.76 bar
Key Takeaways
1 bar = 14.5038 PSI. 1 PSI = 0.0689476 bar. Multiply bar by 14.5038.
THE AUTORANK Editorial Note: European vehicles typically specify tire pressure in bar, while US vehicles use PSI, so always convert before inflating.
