What is a feet to inches converter and how many inches are in a foot?

Feet and inches are the standard units of length in the US customary system. One foot is exactly 12 inches, so converting feet to inches means multiplying by 12. The relationship is fixed by definition, which makes the conversion exact: 3 feet is always 36 inches, and 7.5 feet is always 90 inches. Measurements such as 5 feet 8 inches combine both units, and turning them into total inches makes them easier to compare, add or enter into other calculations.

Converting to inches is useful whenever a job calls for finer precision than feet provide. Carpenters cut trim, studs and shelving to the inch or fraction of an inch. Window and door openings, cabinet dimensions, appliance clearances, pipe runs and fabric are usually listed in inches, while room sizes are measured in feet. Height is another common case, since forms and medical charts sometimes ask for total inches. The most frequent error is treating decimal feet like feet and inches: 5.5 feet is 5 feet 6 inches, not 5 feet 5 inches.

To use this converter, type a length into the Feet box and the result in inches appears as you type. The tool also works backward, so entering a number in the Inches box shows the equivalent in feet. Decimals are accepted, for example 6.25 feet equals 75 inches. For a mixed measurement like 5 feet 8 inches, either convert the feet and add the extra inches yourself (60 + 8 = 68), or enter the feet as a decimal. Results are rounded to two decimal places.

How to convert feet to inches

Multiply the number of feet by 12. Formula: inches = feet × 12. Example: 8 feet × 12 = 96 inches, the height of a standard sheet of drywall or plywood.

For feet and inches together, multiply the feet by 12 and add the remaining inches. Example: 5 ft 10 in = (5 × 12) + 10 = 70 inches. To go from inches back to feet, divide by 12.
