Convert between Pascal, bar, PSI, and more.
Convert between Pascal, bar, PSI, atmosphere, and other pressure units
1 Bar =0.000000 Pounds per sq inch (PSI)
Method: Convert to Pascal (Pa) first, then to target unit
Formula: 1 × 100000 ÷ 6894.76 = 0.000000
1 bar = 100,000 Pa
1 bar = 14.5038 PSI
1 atm = 101,325 Pa
1 atm = 14.6959 PSI
1 atm = 1.01325 bar
1 PSI = 6,894.76 Pa
1 kPa = 1,000 Pa
1 torr = 133.322 Pa
Standard atmospheric pressure: 1 atm = 101.325 kPa = 14.7 PSI
Car tire pressure: ~30-35 PSI (~2-2.4 bar)
Bicycle tire pressure: ~40-80 PSI (~2.8-5.5 bar)
Blood pressure: ~120/80 mmHg
Scuba tank: ~200-300 bar (~3000-4500 PSI)
Pressure is the force applied perpendicular to a surface per unit area. The SI unit is Pascal (Pa), but bar, PSI, and atmosphere are commonly used in different industries. Weather forecasts often use millibar (mbar) or inches of mercury (inHg).
