Brinell and Rockwell Hardness Conversion Chart - These Conversion Tables presents data in the Rockwell A, B, C, D, E and F hardness range on the relationship among Brinell hardness, Vickers hardness, Rockwell and Shore Scleroscope hardness
The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters.
This table shows approximate hardness of steel using Brinell, Rockwell B and C and Vickers scales. These conversion charts are provided for guidance only as each scales uses different methods of measuring hardness. The right hand column show an approximate equivalent tensile strength.
The table below converts Brinell Hardness to Rockwell Hardness scales and vice versa, then compares those to the approximate tensile strength that those scales indicate.
Hardness comparison. A variety of hardness -testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels.

HARDNESS CONVERSION TABLE. For Hardening Carbon and Low Alloy Steel. Numbers in parentheses indicate hardness values, which are outside the definition area of the standard hardness test, but often used as approximate values. The Brinell values in parenthesis are only used when measured with a hard metal ball. Calculated as: HB = 0.95 x HV.
