The hardness is inversely proportional to the depth of penetration. There are many Rockwell hardness scales, depending on the type of indenter and load used. For example, the Rockwell C scale uses a cone-shaped, diamond-tipped indenter with a 150-kg load. The Rockwell B scale uses a 1/16-inch diameter ball indenter with a 100-kg load.
