About this tool
There are exactly 12 inches in a foot, so inches = feet × 12. Decimal feet work the same way: 5.5 ft × 12 = 66 in, and 0.25 ft = 3 in.
Example: someone 5 ft 10 in tall is (5 × 12) + 10 = 70 inches. Decimal feet often come from measuring tools and plans (5.75 ft), while people usually speak in feet and inches (5 ft 9 in) — converting to total inches is the easiest way to compare the two.
