There are many naming conventions for grit measurement. Work Sharp includes the size of the grit in microns as a standard for comparison between abrasives (higher numbers = more coarse). Many other factors contribute to an abrasive’s application and material removing properties, including the shape of the grit, the pattern the grit is applied to the backing material, various characteristics of proprietary abrasive materials used by different manufacturers, etc.
