There is no method of conversion or comparison between Brinell hardness numbers which are obtained by different steel ball and different load respectively but they satisfying a special condition. In this report, using relations obtained in the former report, the relation to convert between Brinell hardness numbers obtained in all conditions was introduced, which was testified by previous experimental results. To convert the hardness number H_1 (the depth of indentation is h_1) or H_1' (the depth of indentation h_1') obtained by a steel ball of radius R_1 and load P_1 and P_1' respectively, to the hardness number H_2 which will be obtained with a steel ball of radius R_2 and load P_2,the conversion equation was given as following : where, [numerical formula]
