我国计量法规定了国家采用国际单位制,非国家法定计量单位应当废除。但目前仍然在文章中出现非法定计量单位,这可能是习惯用法一时改不过来,也可能是对非法定单位如何换算成法定单位不甚了解。为此,将几个常用单位的换算系数介绍如下。 1.压力(压强)、应力SI单位为帕斯卡(Pa) 单位换算系数是: 达因每平方厘米(dyn/cm~2) =0.1Pa 皮兹(Pz) =1000Pa 巴(bar) =10~6dyn/cm~2=10~5Pa 千克力每平方厘米(kgf/cm~2) =0.0980665 MPa 千克力每平方米(kgf/m~2) =9.80665Pa 磅达每平方英尺(Pdl/ft~2) =1.48816 Pa 磅力每平方英尺(1bf/ft~2) =47.8803 Pa 磅力每平方英寸(1bf/in~2) =6894.76 Pa 英吨力每平方英尺(UKtonf/ft~2) =
China’s measurement law stipulates that the state adopts the international system of units, and non-state legal units of measure shall be abolished. However, non-statutory units of measurement still appear in the article at present. This may not be the case with customary usage. It may also be that the non-statutory units are not properly understood as statutory units. To this end, the conversion factor of several commonly used units are described below. 1. The unit of pressure (pressure) and stress SI in Pascal is: dyn / cm ~ 2 = 0.1 Pa Pz = 1000Pa bar = 10 ~ 6dyn / cm ~ 2 = 10 ~ 5 Pa kgf / cm ~ 2 = 0.0980665 MPa kgf / m ~ 2 = 9.80665 Pa = Pd / ft ~ 2 = 1.48816 Pa lbf / ft2 = 47.8803 Pa Ibf / in2 = 6894.76 Pa UK tonf / ft2 =
