Bar to PSI Conversion Chart (Full Reference)

The Conversion Formula

1 bar = 14.5038 PSI. The bar is defined as exactly 100,000 pascals. PSI (pounds per square inch) is derived from the imperial unit system. The two units are used interchangeably in automotive and industrial settings.

For quick mental math: multiply bar by 14.5. This gives a result within 0.03% of the exact answer — accurate enough for any practical purpose.

Bar to PSI Reference Table

All values rounded to two decimal places.

• 0.5 bar = 7.25 PSI (bicycle suspension fork)
• 1.0 bar = 14.50 PSI (road bike tire minimum)
• 1.5 bar = 21.76 PSI (mountain bike tire)
• 2.0 bar = 29.01 PSI (passenger car minimum)
• 2.2 bar = 31.91 PSI (typical passenger car front)
• 2.3 bar = 33.36 PSI (typical passenger car front)
• 2.4 bar = 34.81 PSI (typical SUV front)
• 2.5 bar = 36.26 PSI (high end passenger / some sports cars)
• 2.8 bar = 40.61 PSI (van or light truck)
• 3.0 bar = 43.51 PSI (road bike — high pressure)
• 4.0 bar = 58.02 PSI (heavy truck)
• 6.0 bar = 87.02 PSI (hydraulic tools, air compressors)
• 10.0 bar = 145.04 PSI (industrial pneumatics)

PSI to Bar (Reverse Reference)

To convert PSI to bar, divide by 14.5038. For example: 35 PSI ÷ 14.5038 = 2.41 bar.

• 28 PSI = 1.93 bar
• 30 PSI = 2.07 bar
• 32 PSI = 2.21 bar
• 35 PSI = 2.41 bar
• 36 PSI = 2.48 bar
• 38 PSI = 2.62 bar
• 40 PSI = 2.76 bar
• 44 PSI = 3.03 bar
• 51 PSI = 3.52 bar
• 60 PSI = 4.14 bar

Conclusion

The bar-to-PSI conversion is one of the most practical unit conversions for anyone who services their own vehicle or works with pneumatic equipment. The 14.5 multiplier is easy to remember and accurate enough for all real-world purposes.
