What is PSI?

PSI is a unit of measurement. P refers to pounds, s refers to squares, and I refers to inches. In the United States, it is customary to use psi as the unit, which means pounds per square inch. Changing all units into metric units, we can calculate:1bar ≈14.5psi.

P is a pound, S is a square and I is an inch. Pressure unit; ? Psi is a unit of pressure, defined as pounds per square inch. You can change all units into metric units to calculate: 1bar≈ 14.5psi? ,? 145psi= 1Mpa

All kinds of standard pressure gauges and universal pressure gauges in China generally have MPA and PSI marks. In China, the pressure of gas is generally described by "kg" (not "kg"), and the unit is "kgf/cm2". One kilogram of pressure means that one kilogram of force acts on one square centimeter.

All kinds of standard pressure gauges and universal pressure gauges in China generally have MPA and PSI marks. In China, the pressure of gas is generally described by "kg" (not "kg"), and the unit is "kgf/cm2". One kilogram of pressure means that one kilogram of force acts on one square centimeter.

The conversion relationship is:1kg/cm2 = 0.98bar = 98.0665kpa =14.2psi.1atmospheric pressure = 1.03327 kg/cm2. In order to facilitate the memory and conversion, the commonly used kg/cm2, bar and cm2 are adopted.
