METRIC EQUIVALENTSX1.1 The SI unit for strength properties now shown is inaccordance with the International
26、System of Units (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
27、 (N/m2), which 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/m2 and N/mm2.SUMMARY OF CHANGESCommittee B05 has identified the location of selected changes to
