How to Calculate Hardness Converter
What is Hardness Converter?
Hardness converters translate between different material hardness scales: Rockwell, Brinell, Vickers, Shore, and others.
Step-by-Step Guide
- 1Rockwell: A, B, C scales (different indenters, loads)
- 2Brinell: BHN (ball indenter), larger impression
- 3Vickers: Very hard materials, diamond indenter, small load
Worked Examples
Input
Steel 50 HRC (Rockwell C)
Result
Approximately 475 HV (Vickers), 450 HB (Brinell)
Approximate conversions
Common Mistakes to Avoid
- ✕Treating conversions as exact (they're approximations)
- ✕Using wrong scale for material (Rockwell inappropriate for very soft/hard materials)
Frequently Asked Questions
Which hardness scale is most reliable?
Vickers most precise for hard materials, Brinell for softer. Different scales measure different things.
Does hardness relate to tensile strength?
Generally yes, but not directly. Hardness and strength both measure resistance to deformation differently.
