The wear factor can be manipulated to calculate the often more convenient and more physically direct specific wear rate (also known as a dimensional wear rate ), k, commonly measured in units of mm3/Nm . The specific wear rate is simply the wear volume divided by the product of the normal load and the sliding distance, d, as shown:
