The most frequently used pressure units
The most frequently used pressure units 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.
Bar is a metric pressure unit and equals to 100 kilopascals which is almost equal to the atmospheric pressure.
Inch of Mercury Conversion:
Inch of Mercury (inHg) is the pressure exerted by a column of mercury 1 inch (25.4 mm) in height.
Kilopascal (kPa) Conversion:
Kilopascal (kPa) is a frequently used pressure unit and equals to 1000 newton per square meter (metre).
Pascal is a derived metric pressure unit and equals to 1 newton per square meter.
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.
