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.
Pascal is a derived metric pressure unit and equals to 1 newton per square meter.
Kilopascal (kPa) Conversion:
Kilopascal (kPa) is a frequently used pressure unit and equals to 1000 newton per square meter (metre).
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.
