The inches to feet conversion factor
Twelve inches equal exactly 1 foot, so to convert inches to feet you divide by 12: feet = in ÷ 12. For example, 36 in ÷ 12 = 3 feet. To go the other way, use the feet to inches calculator.
The relationship is exact by definition, not a rounded factor, so no accuracy is lost in either direction. From it follow the other imperial lengths: 36 inches make a yard, and 63,360 inches make a mile.
How to convert inches to feet
Enter a length in inches and the calculator divides by 12 to return feet. This helps with measuring rooms, furniture, and height. Results show up to four decimal places when a value is not a whole number of feet.
Worked example: a worktop measures 92 inches. Dividing by 12 gives 7.6667 ft, which reads as 7 ft 8 in because 0.6667 x 12 = 8. Decimal feet are what you want for area and cost calculations; feet and inches are what you want when reading a tape measure or quoting a height.
A common trap is mixing the two formats in one sum. Adding 5.8 ft to 5 ft 8 in is not the same thing at all - 5 ft 8 in is 5.67 ft, not 5.8. Convert everything to decimal feet first, add, then convert back at the end.
The inches to cm calculator handles the closely related case.

Handy landmarks: a standard interior door is 80 in, or 6.67 ft; a queen mattress is 80 in long and 60 in wide, so 6.67 ft by 5 ft; and a sheet of plywood at 96 x 48 in is exactly 8 ft by 4 ft.
