METRIC EQUIVALENTSX1.1 The SI unit for strength properties now shown is inaccordance with the International System of U
30、nits (SI). Thederived SI unit for force is the newton (N), which is defined asthat 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), wh
31、ich has beennamed the pascal (Pa) by the General Conference on Weightsand Measures. Since 1 ksi = 6 894 757 Pa the metric equiva-lents are expressed as megapascal (MPa), which is the same asMN/m2and N/mm2.SUMMARY OF CHANGESCommittee B05 has identified the location of selected changes to this standar
