How do you read a metal screw size?

In the Unified Thread Standard (UTS) system, manufacturers list the diameter size as a number between 0 and 10, with 0 being the smallest and 10 being the largest. Screws larger than a #10 have a diameter listed directly in inches. For example, on a #4-40 UNC-3A x . 5 screw, #4 represents the diameter.
