Write down two values you want to convert from inches to 16ths of an inch, for example, 0.5 and 5.
Determine the number of smaller units per unit of the larger quantity. In this case, there are 16 units of smaller quantity (1/16 inch) in one unit of the larger quantity.
Multiply the larger-quantity amount by the number of smaller units per unit of the larger quantity. Multiplying 16 by 0.5 gives you 8, so 8/16 equals 0.5 inches. Multiplying 16 by 5 gives you 80, meaning 80/16 equals 5 inches.
