Each unit being one-sixteenth of an inch (1/16th inch). These small 16 units are grouped into larger units called: 1/8th inch which consists of 2/16ths (2/16ths being mathematically reduced to 1/8th). Two of these 1/8th units are 1/4th inch (also commonly called a quarter of an inch). Two of these 1/4th divisions equal ½ inch (again, 2/4ths being mathematically reduced to ½).
