1、有关压力单位PSI和BAR之间的区别，PSI和BAR是什么压力单位磅力每平方英寸(ibf/in2)为1psi=6894.76pa；1bar等于10的5次方=105pa；1atm等于一个标准大气压=101325pa；1at等于一工程大气压(千克力每平方厘米kgf/cm2)=98066.5pa，以上均为不同场合使用的压单位，相互可换算15个psi约为一个大气压张铁垣主编的分析化学中的量和单位第二版中指出过去使用许多压力单位均应废除，统一标准压力单位为pa,其译名为帕斯卡为一个压力单位，所以全部压力单位均向pa转换。根据以上换算取四位有效数1psi=14.50bar1个标准大气压=14.69psi1
