Units Defined in Pressure
Below is the complete registry of units supported within the conversion tool.
Pascal
Pa, pascal, pascalsThe SI derived unit of pressure, equal to 1 Newton per square meter.
Bar
bar, barsMetric unit of pressure defined as exactly 100,000 Pascals (approx. atmospheric pressure at sea level).
PSI (Pounds per Square Inch)
psi, lbs/sq inUS customary unit of pressure, representing pound-force applied to 1 square inch.
Atmosphere
atm, atmosphere, atmospheresReference pressure defined as mean sea-level atmospheric pressure (101,325 Pa).
Torr
Torr, torr, mmHgA unit of pressure defined as 1/760 of an atmosphere, very close to 1 millimeter of mercury.
