Pressure Converter

Unit Converters

Pa, kPa, MPa, bar, atm, psi

Quick Answer

Pressure Converter: Pa, kPa, MPa, bar, atm, psi. Pressure Converter uses standard unit conversion formulas to compute accurate results instantly.

1 atm = 101325 Pa = 760 mmHg = 14.696 psi · 1 bar = 100 kPa
101.325000Kilopascal (kPa)

1 Atmosphere (atm) = 101.325000 Kilopascal (kPa) · 1 Kilopascal (kPa) = 0.009869 Atmosphere (atm)
