Hardness Conversion Tool
An essential tool for metallurgists and QC inspectors. Convert between common hardness scales like Rockwell, Brinell, and Vickers. Note: These are approximations.
Enter Hardness Value
Enter a value in one scale to see its approximate equivalent in others.
Understanding Material Hardness
Hardness is a material's ability to resist localized plastic deformation, such as a scratch or indentation. It's a critical property in metallurgy and material science, as it often correlates with tensile strength and wear resistance. Several different tests and scales are used to measure hardness, each with its own advantages.
