Converts between Vickers (HV), Brinell (HB), and Rockwell C/B scales for metals using empirical conversion equations. HV ≈ HB below 300; above this they diverge — Vickers uses a diamond pyramid and is valid from very soft materials to hardened ceramics.
Inputs
Hv
Reference formula or conversion factor shown for context.
