mpa、psi、bar与大气压的换算相关标签:

    工程上常用的是兆帕( MPa ): 1MPa=1000000Pa 。 1 个标准大气压力 =1.00336 0.098MPa=0.10108MPa 0.1Mpa 。 1bar=0.1MPa 压力的法定单位是帕斯卡( Pa ): 1Pa=1N/ ㎡(牛顿 / 平方米)。 压力单位换算: 1MPa=1000kPa 1kPa=10mbar=101.9716 mmH2O = 4.0
    工程上常用的是兆帕(MPa):1MPa=1000000Pa。
    1个标准大气压力=1.00336×0.098MPa=0.10108MPa≈0.1Mpa。
    1bar=0.1MPa
    压力的法定单位是帕斯卡(Pa):1Pa=1N/㎡(牛顿/平方米)。
    压力单位换算:
    1MPa=1000kPa
    1kPa=10mbar=101.9716 mmH2O = 4.01463imH2O
    10mWC=1bar=100kPa
    bar 巴 = 0.987 大气压 = 1.02 千克/平方厘米 = 100 千帕 = 14.5 磅/平方英寸  
    PSI英文全称为Pounds per square inch。P是磅pound,S是平方square,I是英寸inch。把所有的单位换成公制单位就可以算出:1bar≈14.5psi
    1psi=6.895kPa=0.06895bar
    1兆帕(MPa)=145磅/英寸2(psi)=10.2千克/厘米2(kg/cm2)=10巴(bar)=9.8大气压(atm)
    1磅/英寸2(psi)=0.006895兆帕(MPa)=0.0703千克/厘米2(kg/cm2)=0.0689巴(bar)=0.068大气压(atm)
    1巴(bar)=0.1兆帕(MPa)=14.503磅/英寸2(psi)=1.0197千克/厘米2(kg/cm2)=0.987大气压(atm)
    1大气压(atm)=0.101325兆帕(MPa)=14.696磅/英寸2(psi)=1.0333千克/厘米2(kg/cm2)=1.0133巴(bar)
