41、 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 onekilogram gives it an acceleration of one metre pe
42、r secondsquared (N = kg m/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 Measures. Since 1 ksi = 6 894 757 Pa, the metric equiva-lents are expressed as megapascal (MPa), which is the sa
43、me asMN/m2and N/mm2.SUMMARY OF CHANGESCommittee B05 has identified the location of selected changes to this standard since the last issue (B 422 05)that may impact the use of this standard.
