Pressure Conversion Calculator
Convert between pressure units: PSI, bar, pascal, atmosphere, torr, mmHg, kPa, MPa, and more. Accurate pressure unit conversions for engineering, science, and industrial applications.
Step 1: Enter Pressure Value
Understanding Pressure Units
Pressure is force per unit area. Common units: PSI (pounds per square inch), bar (metric unit equal to 100 kPa), Pascal (SI unit, 1 N/m²), atm (Earth’s atmospheric pressure at sea level).
Step 2: Calculation Options
Common Pressure Conversions
1 atm = 101.325 kPa = 14.696 psi = 760 mmHg
1 bar = 100 kPa = 14.5038 psi
1 psi = 6.89476 kPa = 0.0689476 bar

Pressure Conversion Formulas
PSI to Other Units
PSI to bar: bar = PSI × 0.0689476
PSI to kPa: kPa = PSI × 6.89476
PSI to atm: atm = PSI × 0.068046
PSI to mmHg: mmHg = PSI × 51.7149
Bar to Other Units
Bar to PSI: PSI = bar × 14.5038
Bar to kPa: kPa = bar × 100
Bar to atm: atm = bar × 0.986923
Bar to MPa: MPa = bar × 0.1
Atmosphere to Other Units
Atm to PSI: PSI = atm × 14.696
Atm to bar: bar = atm × 1.01325
Atm to kPa: kPa = atm × 101.325
Atm to mmHg: mmHg = atm × 760
Pascal (SI Unit)
1 Pascal = 1 Newton per square meter (N/m²)
1 kPa = 1,000 Pa
1 MPa = 1,000,000 Pa
1 GPa = 1,000,000,000 Pa
