To convert the Vickers hardness number to SI units the hardness number in kilograms-force per square millimeter (kgf/mm ) has to be multiplied with the standard gravity, , to get the hardness in MPa (N/mm ) and furthermore divided by 1000 to get the hardness in GPa. Vickers hardness can also be converted to an SI hardness based on the projected area of the indent rather than the surface area. The projected area, , is defined as the following for a Vicker… NettetThe minerals contained in the scale are shown in the Table; also shown are other materials that approximate the hardness of some of the minerals.
