Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types.Note! - pressure is "force per unit area" and commonly used pressure units like kg/cm 2 and similar are in principle not correct since kg is a mass unit. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. Since atmospheric pressure at sea level is around 14.7 psi, this will be added to any pressure reading made in air at sea level.Ĭonversion calculator for all types of measurement units.
Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher. The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The definition of a pascal is as follows: The SI prefix "kilo" represents a factor of Psia to kPa, or enter any two units below: Enter two units to convert From: You can do the reverse unit conversion from
