44、IX(Nonmandatory Information)X1. 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 asthat force which when applied to a body having a mass of 1 kggives it a
45、n acceleration of 1 m/s2(N = kgm/s2). The derived SIunit for pressure or stress is the newton per square metre(N/m2), which has been named the pascal (Pa) by the GeneralConference on Weights and Measures. Since 1 ksi = 6 894 757Pa, the metric equivalents are expressed as megapascal (MPa),which is th
46、e same as MN/m2and N/mm2.SUMMARY OF CHANGESCommittee B05 has identified the location of selected changes to this standard since the last issue(B 570 05a) that may impact the use of this standard.
