Material Hardness

Material hardness is measured using a variety of scales in research as well in industrial applications. The choice of scale depends on the level of hardness needing measured. The Mohs hardness scale is one of the more commonly recognized and was designed to measure the hardness of minerals by using one mineral to scratch another. Additional hardness scales have been developed for different applications with some being finer grained than others. Investigate, using Wolfram|Alpha, additional hardness scales, such as Rockwell, Brinell, Knoop, and Vickers.
Material Hardness

Convert between various hardness scales by specifying a scale and value or by requesting a specific formula.

Convert a specific material hardness to various other systems:

Mohs 6.5
Rockwell c hardness number 70

Convert a material hardness number into a specific system:

convert Rockwell c 44 to Brinell

Compute with hardness systems based on formulas:

Brinell hardness formula 3000 kgf, 10 mm, 2.5 mm
Knoop hardness formula 300 gf, 3.37 mm, Cp=0.070279
Vickers hardness formula 30 kgf, 0.5 mm
