Wrap the pi tape around the piece to be measured, with the numbers facing outward. Line up the two sets of numbers. On the 0 25 scale find where the 0 lines up with the other scale. That is the diameter to the nearest inch and hundredth of an inch. From the 0 25 and the inch scale, find the two lines that line up best and the reading on the 0 25 scale is the thousandths of an inch.
