PASCAL and other conversion relationship between the pressure units

The pressure unit in the international system of units is n/m & sup2; , also known as PASCAL, referred to as '& quot; Palmer & quot; ( Expressed in Pa) 。 Its physical meaning is: a Newton force evenly applied to the vertical pressure produced by square meters area. The Pa = N/m&sup 2; Type: Pa— — PASCAL ( Pressure unit) N— — Newton ( Unit of force) m— — M ( The length of the unit) Due to historical reasons, the use of more pressure units. Although our country has stipulated can only use si units & ndash; — PASCAL, but with the opening to the outside world and the technology import, our country has many units with equipment imported pressure instrument has many is made of legal measurement units thought pressure unit in China. In order to facilitate conversion here introduce a few kinds of common pressure unit conversion relations with PASCAL: 1 hpa ( Hundred mpa) = 100 pa ( Palmer) 1 kpa ( Kpa) = 1000 pa ( Palmer) 1MPa（ Hundred mpa) =1000000Pa（ Palmer) 1bar（ Ba) =100000Pa（ Palmer) 1mbar（ Millibars) = 100 pa ( Palmer) 1 psi ( Pounds per square inch) = 6894. 76Pa（ Palmer) 1kgf/cm² （ KGF/cm2) = 98066. 5Pa（ Palmer) 1毫米汞柱( Mm hg) = 133. 322Pa（ Palmer) 1mmH2O（ Mm water column) = 9. 80665 pa ( Palmer)
