Hardness Conversion Calculator | Rockwell, Brinell & Vickers Tool

Hardness Tool Formula:

Brinell (HB) to Rockwell (HRC):

\[ HRC = 0.0275 \times HB - 1.707 \]

Rockwell (HRC) to Brinell (HB):

\[ HB = 37.25 \times HRC + 2.49 \]

Rockwell (HRC) to Vickers (HV):

\[ HV = 10 \times HRC + 100 \]

The Hardness Conversion Calculator is a tool that assists engineers, quality control professionals, and students in changing the amount of material hardness among various scales. Hardness is a very important characteristic in terms of mechanical strength, wear resistance and choice of material and different scales are employed depending on the testing method.

Rockwell (HRA, HRB, HRC), Brinell (BHN), Vickers (HV) or Shore (HS) can be typed in by the user. The calculator transforms them into corresponding values in other scales by use of empirical correlation formulas and customary conversion tables. Instructional solutions provide stepwise methods of calculating equivalent hardness values of metals, alloys, plastics, and elastomers and hence one can easily compare materials and make the right choice when using them in the engineering field.

SI units are helped where needed and reports are given in Rockwell, Brinell, Vickers and Shore scales. This is a good tool to use by mechanical engineers, metallurgists, material scientists and students, which is the correct conversion to hardness and the material evaluation.
