There are several hardness scale conversion systems, including BS 860 and ASTM E140.

The table shows a set of values that has been used for stainless steel and also includes a tensile strength (Ultimate Tensile Strength) comparison. The Rockwell B values are superimposed on this table using an approximation from ASTM E140 Table5, which compares Rockwell B and Brinell.

For the indentation methods the different measurements in HV, HRC and HB can also be compared without too much of insecurity. However, for the rebounding methods like Shore and Equotip the errors when making conversions are larger as the individual measurements are highly influenced by the material properties such as internal stresses. Forged rolls have higher internal superficial compression than cast rolls. This creates a higher rebound so the conversion can not be done based on the same tables.
