1kgm＝9.8Nm＝7.2313725lb-ft

1Nm=0.102kgm=0.7376lb-ft

1lb-ft=0.1382863kgm＝1.356Nm

1kgm > 1lb-ft > 1Nm

一標準大氣壓＝1.0339285kg/cm^2=1.0132499bar

1bar=1.0197162kg/cm^2=14.503774PSI

1kg/cm^2=0.980665bar=14.223344PSI

1PSI=0.06894757bar=0.070306955kg/cm^2

1bar > 1kg/cm^2 > 1PSI

1bar、1kg/cm^2和一標準大氣壓是基本相同的
