The most frequently used pressure units

The most frequently used units of pressure are pascal (Pa), kilopascal (kPa), megapascal (MPa), psi (pound per square inch), torr (mmHg), atm (atmospheric pressure) and bar.

Atm (Atmospheric Pressure) Conversion:

An atmosphere (atm) equals to the air pressure at the sea level at a temperature of 15 Celsius.

• 1 atm = 1.01325 bar → atm to bar
• 1 atm = 101.325 kPa → atm to kPa
• 1 atm = 101325 pascals → atm to pascal
• 1 atm = 0.101325 MPa → atm to MPa
• 1 atm = 14.6959 psi → atm to psi
• 1 atm = 760 torr (mmHg) → atm to torr

Bar Conversion:

Bar is a metric pressure unit and equals to 100 kilopascals which is almost equal to the atmospheric pressure.

• 1 bar = 0.986923 atm → bar to atm
• 1 bar = 29.529983071 inHg → bar to inHg
• 1 bar = 1.019716213 kg/cm² → bar to kg/cm²
• 1 bar = 100 kPa → bar to kPa
• 1 bar = 1000 millibars → bar to millibar
• 1 bar = 100000 pascals → bar to pascal
• 1 bar = 0.1 MPa → bar to MPa
• 1 bar = 14.5038 psi → bar to psi
• 1 bar = 750.062 torr (mmHg) → bar to torr

Inch of Mercury Conversion:

Inch of Mercury (inHg) is the pressure exerted by a column of mercury 1 inch (25.4 mm) in height.

• 1 inHg = 3.3863886667 kPa → inHg to kPa
• 1 inHg = 33.863886667 millibars → inHg to millibars

Kilopascal (kPa) Conversion:

Kilopascal (kPa) is a frequently used pressure unit and equals to 1000 newton per square meter (metre).

• 1 kPa = 0.00986923 atm → kPa to atm
• 1 kPa = 0.01 bar → kPa to bar
• 1 kPa = 0.01019716213 kg/cm² → kPa to kg/cm²
• 1 kPa = 0.001 MPa → kPa to MPa
• 1 kPa = 1000 pascals → kPa to pascal
• 1 kPa = 0.145038 psi → kPa to psi
• 1 kPa = 7.50062 torr (mmHg) → kPa to torr

Pascal Conversion:

Pascal is the unit of pressure in the metric system and is equal to 1 newton per square meter.

• 1 pascal = 0.000009869 atm → pascal to atm
• 1 pascal = 0.00001 bar → pascal to bar
• 1 pascal = 0.01 kPa → pascal to kPa
• 1 pascal = 0.000001 MPa → pascal to MPa
• 1 pascal = 0.000145 psi → pascal to psi
• 1 pascal = 0.0075 torr (mmHg) → pascal to torr

Psi (Pound Force Per Square Inch) Conversion:

Psi is a pressure unit and equals to the force of one pound applied to one square inch.

• 1 psi = 0.068046 atm → psi to atm
• 1 psi = 0.0689476 bar → psi to bar
• 1 psi = 2.0360206576 inHg → psi to inHg
• 1 psi = 0.07030695783 kg/cm² → psi to kg/cm²
• 1 psi = 6.89476 kPa → psi to kPa
• 1 psi = 0.00689476 MPa → psi to MPa
• 1 psi = 6894.76 pascals → psi to pascal
• 1 psi = 51.715 torr (mmHg) → psi to torr
