Help on converting Pressure Units
The units of pressure most commonly used and converted are the following:
- pascal (Pa), kilopascal (kPa), megapascal (MPa)
- psi (pound per square inch)
- torr (mmHg)
- atm (atmospheric pressure)
- bar
Wondering how to convert atm to mmHg and what is atm?
An atmosphere (atm) is a unit of measurement and equals to the air pressure at sea level, at a temperature of 15 Celsius.
- atm to bar → 1 atm = 1.01325 bar
- atm to psi → 1 atm = 14.6959 psi
- atm to torr → 1 atm = 760 torr (mmHg)
- atm to kPa → 1 atm = 101.325 kPa
- atm to Pa → 1 atm = 101325 pascals
- atm to MPa → 1 atm = 0.101325 MPa
Do you want to know what is bar and how to convert bar to psi in one simple move?
Bar is a metric pressure unit, although not a part of the official International System of Units (SI).
It equals to 100 kilopascals which is almost equal to the atmospheric pressure.
- bar to millibar → 1 bar = 1000 millibars
- bar to atm → 1 bar = 0.986923 atm
- bar to psi → 1 bar = 14.5038 psi
- bar to torr → 1 bar = 750.062 torr (mmHg)
- bar to kPa → 1 bar = 100 kPa
- bar to Pa → 1 bar = 100000 pascals
- bar to MPa → 1 bar = 0.1 MPa
- bar to inHg → 1 bar = 29.529983071 inHg
- bar to kg/cm² → 1 bar = 1.019716213 kg/cm²
Interested in learning what is mmHg and how to convert it to other pressure units?
A millimeter of mercury is a manometric unit of pressure, defined as exactly 133.322387415 pascals.
- mmHg to atm → 1 mmHg = 0.0013157858376511226 atm
- mmHg to bar → 1 mmHg = 0.00133322 bar
- mmHg to kPa → 1 mmHg = 0.133322 kPa
- mmHg to Pa → 1 mmHg = 133.322 Pa
Do you know what is a Pa? Pascal is a unit of pressure in the metric system, equal to 1 newton per square meter. It has several multiples and sub-multiples that are formed using the standard SI units that are also commonly used.
Commonly used multiples of Pascal: hectopascal (hPa), kilopascal (kPa) and megapascal (MPa), Commonly used sub-multiples: milipascal (mPa), nanopascal (nPa) etc.
- Pa to kPa → 1 pascal = 0.01 kPa
- Pa to MPa → 1 pascal = 0.000001 MPa
- Pa to atm → 1 pascal = 0.000009869 atm
- Pa to bar → 1 pascal = 0.00001 bar
- Pa to psi → 1 pascal = 0.000145 psi
- Pa to torr → 1 pascal = 0.0075 torr (mmHg)
Learning how to convert psi to bar is rather easy!
Psi is a pressure unit and equals to the force of one pound applied to one square inch.
- psi to atm → 1 psi = 0.068046 atm
- psi to bar → 1 psi = 0.0689476 bar
- psi to kpa → 1 psi = 6.89476 kPa
- psi to Pa → 1 psi = 6894.76 pascals
- psi to Mpa → 1 psi = 0.00689476 MPa
- psi to torr → 1 psi = 51.715 torr (mmHg)
- psi to inhg → 1 psi = 2.0360206576 inHg
- psi to kg/cm² → 1 psi = 0.07030695783 kg/cm²
