METRIC EQUIVALENTSX1.1 The SI unit for strength properties now shown is inaccordance with the International System of Units (SI). Thederived SI unit for force is the newton (N), which is defined as
40、that force which when applied to a body having a mass of onekilogram gives it an acceleration of one metre per secondsquared (N = kgm/s2). The derived SI unit for pressure orstress is the newton per square metre (N/m2), which has beennamed the pascal (Pa) by the General Conference on Weightsand Meas
41、ures. Since 1 ksi = 6 894 757 Pa the metricequivalents are expressed as megapascal (MPa), which is thesame as MN/m2and N/mm2.TABLE 3 Electrical ResistivityTemper Copper Alloy UNS No. C18080Electrical Resistivityat 20C (68 F),Equivalent Conductivityat 20C (68 F),Vg/m % IACSTM04, TM08 0.20437 min. 75
