eFunda: Convert Hardness: Vickers - eFunda: The Ultimate Online Reference for Engineers Symbol: HV The Vickers Hardness test can be applied to different materials across a very wide range of hardnesses. The Vickers test uses a square-based diamond pyramid with a 136º point angle. The load (usually 50 kgf, but could be 5, 10, 20, 30, or 120 k

Calculator for Conversion between Vickers Hardness Number and SI Units MPa and GPa There is now a trend towards reporting Vickers hardness in SI units (MPa or GPa) particularly in academic papers. Unfortunately, this can cause confusion. Vickers hardness (e.g. HV/30) value should normally be expressed as a number only (without the units
