How the feet to inches converter works
Type a length in feet to see the total number of inches immediately. The conversion also works backwards, and either unit menu can switch to other common length measures.
Each foot contains exactly twelve inches
Feet and inches belong to the same measurement system, so the relationship is a whole number rather than a rounded decimal. Multiply feet by 12; divide inches by 12 to return to feet.
Useful values for a quick check
0.5 ft = 6 in. Half a foot is six inches.
3 ft = 36 in. This is a familiar width for a doorway or work surface.
8 ft = 96 in. An eight-foot length contains ninety-six inches.
Mixed feet-and-inches measurements need one extra step
A written length such as 5 ft 8 in contains two parts. Convert the feet first, then add the remaining inches: 5 × 12 + 8 = 68 inches.
Decimal feet follow the same rule. For example, 2.25 ft × 12 = 27 in. Keep decimals only when the original measurement is precise enough to justify them.
