Pressure Conversion
1 bar = 14.5 PSI = 100,000 Pa | 1 atm = 101,325 Pa
Pressure = force/area. Base SI unit is Pascal (Pa). 1 Pa = 1 N/m².
Frequently Asked Questions
1 PSI = 0.069 bar. Multiply PSI by 0.069. Example: 30 PSI = 2.07 bar. Car tires: 30-35 PSI = 2.0-2.4 bar.
1 atm = 101,325 Pa = 1.013 bar = 14.7 PSI = 760 mmHg. Standard pressure at sea level.
1 bar = 14.5 PSI. Multiply bar by 14.5. Example: 2.5 bar = 36.3 PSI.
Gauge is relative to atmospheric (0 at sea level). Absolute includes atmospheric. Absolute = Gauge + 1 atm.
