In addition, one can also get more exact results by seeing if both minerals scratch each other. We can add another step to the chart above for those that have hardness testing kits composed of minerals rather than rods: ... Mineral hardness is 3.

Mohs Scale of Mineral Hardness ... In 1812 the Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs (1773-1839), who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary.

There are many different scales / methods to measure mineral hardness. The most appropriate method for your application will depend on the material that you are measuring. The chart below is intended to give you a general reference of how some of these methods relate to others, using Mohs as the base measurement.
