A measure of the ability of a grinding wheel to remove material is given by G-ratio. An efficient hard wearing grinding wheel will grind an easy-to-grind material for a long time with only a small amount of wheel wear. This corresponds to a high G-ratio. The grinding ratio G is defined as volume of material removed divided by volume of wheel wear.
