在截止閥管件行業(yè)中，根據(jù)公稱壓力PN的大小，我們可以把公稱壓力小于等于1.6MPa的閥門為低壓閥門，公稱壓力為2.5MPa、4.0MPa、6.4MPa的閥門為中壓閥門，同時(shí)我們也經(jīng)常會(huì)提到1.6MPa壓力、2.5MPa壓力和多少公斤壓力、多少個(gè)標(biāo)準(zhǔn)大氣壓等之類的術(shù)語(yǔ)，那么1MPa壓力到底有多大壓強(qiáng)，1MPa壓力等于多少公斤壓力呢蒸汽壓力為2.5㎏是表示2.5kg/cm2，是表示的單位面積上的壓力--壓強(qiáng)，通常俗稱為2.5kg壓力。新的表示方法約為0.25MPa。
換算關(guān)系：1kg/cm2=0.098MPa，因此壓力2.5kg/cm2=0.245MP，可約等于0.25MPa.ISO標(biāo)準(zhǔn)帕斯卡(1Pa=1N/m2)
1公斤力/平方厘米=98.0665千帕
粗算時(shí)常按1公斤力=10N 則:
1公斤力/平方厘米=100千帕=1bar=0.1MPa
10公斤力/平方厘米=1000千帕=1MPa
公斤的單位是質(zhì)量單位
MPA是壓力的單位
質(zhì)量m=壓力/重力加速度
壓力p=壓力/面積
這是他們之間的關(guān)系

1公斤壓力指的是1公斤重的物體作用為1cm2面積上所產(chǎn)生的壓強(qiáng)，可以想像一下，1公斤重（比兩瓶一元錢的康師傅礦泉水重略輕）的物體全部壓在一個(gè)手指頭上所產(chǎn)生的壓強(qiáng)。  我們來(lái)計(jì)算一下， 1MPa=1×106Pa 1Pa=1N/1m2  1MPa=106N/m2=106N/104cm2=100N/cm2  重力加速度g約等于9.8 N/KG，為方便計(jì)算，g按整數(shù)10。 1KG的物體重力=1KG×10N/KG=10N  1公斤壓力是1KG的重力作用于1cm2面積上產(chǎn)生的壓強(qiáng)，即 1公斤壓力=10N/cm2 1MPa=100N/cm2=10×10N/cm2 即1MPa壓力等于10公斤壓力。
單位說(shuō)明：  Pa，壓強(qiáng)單位，中文名稱為“帕斯卡"，簡(jiǎn)稱“帕"，即牛/平方米，1帕=1牛/平方米  M，數(shù)量單位，M即million，數(shù)值為一百萬(wàn)  N，物理力學(xué)單位，簡(jiǎn)稱牛，是一種衡量力的大小的單位，兩個(gè)雞蛋的重力約為1N（0.1千克的物體的重量）  m，長(zhǎng)度單位，米 m2，面積單位，平方米 cm2，面積單位，平方厘米 KG，重量單位，千克，公斤
