Quick Answer:
1 PSI = 0.0689476 bar. To convert PSI to bar, multiply the PSI value by 0.0689476.
PSI and bar are the primary pressure units for tires, hydraulics, and weather.
Detailed Overview: PSI to Bar
PSI (pounds per square inch) is an imperial pressure unit. Bar is a metric pressure unit equal to 100,000 pascals. 1 PSI = 0.0689476 bar. 1 bar = 14.5038 PSI. Multiply PSI by 0.0689476 for bar. Multiply bar by 14.5038 for PSI. Used in tire pressure, scuba tanks, and hydraulic systems.
Conversion Reference Table
1 PSI = 0.0689 bar, 5 PSI = 0.3447 bar, 10 PSI = 0.6895 bar, 20 PSI = 1.3790 bar, 32 PSI = 2.2063 bar, 50 PSI = 3.4474 bar, 100 PSI = 6.8948 bar
Practical Calculation Example
Convert 35 PSI: bar = 35 × 0.0689476 = 2.41 bar. Reverse: 3 bar = 3 × 14.5038 = 43.51 PSI
Key Takeaways
1 PSI = 0.0689476 bar. 1 bar = 14.5038 PSI. Multiply PSI by 0.0689476 for bar.
THE AUTORANK Editorial Note: Tire pressure gauges often show both units, but always verify which unit your vehicle manual specifies.
