Overview
Hardness is a material's resistance to localized deformation. Different scales use different indenters and loads, so exact conversion is not finding a formula but using empirical tables.
💡
Pro Tips
This calculator uses standard approximations for non-austenitic steels.
Conversions are approximate and should not replace actual testing.
The Rockwell C scale uses a diamond cone indenter and 150kg load.

Fun Facts
"Diamond is 10 on the Mohs scale, which is much simpler than these engineering scales."
"HRC is most commonly used for hardened steel (knives, tools)."
