Calculate your baseline first
Multiply the number of feet by 12, then add any extra inches. For example, 5 feet 8 inches is 5 × 12 + 8 = 68 inches.
Yes. The inches field accepts decimal values, so a measurement like 5 ft 7.5 in converts to 67.5 total inches.
Traditional feet-and-inches notation keeps the inches remainder below 12. If you have 13 inches, that is 1 foot 1 inch. This tool flags values outside the standard remainder range.
