Surrounded by a thick layer of the Earth's surface atmospheric pressure on the Earth's surface or the surface of the object caused called "pressure." Symbol pb;
Acts directly on the surface of the pressure vessel or object, called "absolute pressure", the absolute value of an absolute vacuum pressure as a starting point, the symbol for pa;
Measured out with pressure gauge, vacuum gauge, U-shaped pipe pressure instrument called "gauge pressure", "gauge pressure" as a starting point to atmospheric pressure, the sign bit pg.
The relationship between the three is Pa = pb + pg
Pressure is the force per unit area of a pressure unit N/m2, denoted by pa, called Pascal.
Widely used in engineering MPa (MPa)
1MPa = 106Pa
1 atm = 0.1013MPa
1kPa = 1000Pa = 0.01kgf/cm2
1MPa = 106Pa = 10.2kgf/cm2
In the old system of units, the pressure is usually kgf/cm2 (kgf / cm) for the unit.
People often daily work habits to describe the amount of pressure in kilograms, they are translated into:
1 kg = 1Bar = 0.1Mpa
