In the former report, the author had analyzed the cone indentation hardness by the condition of balancing between indenting load and the stresses at the contact surface. In this paper, the ball indentation hardness is cralified from the same point of view assuming the contact pressure on the basis of the results for several kinds of punch indentation. To check the theoretical relations between the indenting load, ball diameter, yield stress of specimen and the depth or the diameter of indentation, indentations were made upon many kinds of specimen with different hardness. From this relations, both the theoretical conversion between H_R or H_RT and H_V, between H_B and H_V, between H_R or H_RT and H_B, and the equations of errors of H_R or H_RT arisen from the errors of load and ball diameter were induced. At last, the Meyer's law was studied theoretically by this relation.
