Rockwell scale - Wikipedia

The chief advantage of Rockwell hardness is its ability to display hardness values directly, thus obviating tedious calculations involved in other hardness measurement techniques. The equation for Rockwell Hardness is H R = N − d s {\displaystyle HR=N-{\frac {d}{s}}} , where d is the depth (from the zero load point), and N and s are scale ...
