Hardness Conversion Formula. Y = aX^2 + bX + c. Where: Y is the hardness value in the target scale; X is the hardness value in the original scale; a, b, and c are constants determined through empirical testing; Example: Converting Brinell (HB) to Rockwell C (HRC) for steels:. HRC = -0.000000567 HB^2 + 0.0624 HB – 13.7. Using this formula, we can convert a Brinell hardness .Unmatched versatility owed to HV1, HV5, and HV10 test loads in one wireless probe .
