Convert feet to inches
Enter a value in feet and read the result in inches straight away. Feet turn into inches most often for height, equipment sizes and screen diagonals. Watch the height notation, though: 5 feet 7 inches is not the same as 5.7 feet. A separate table lower down shows how many inches a height in feet and inches comes to.
Why convert feet to inches?
Feet and inches sit side by side in everyday measuring, so you convert whenever a value in feet has to read in the finer unit: a height you want stated in inches, a size you need to compare with a screen diagonal, or a dimension given in feet where you want the exact inch figure.
The relationship is simple and exact: one foot is 12 inches. To turn feet into inches, you multiply the number of feet by 12. The converter does that for you the moment you type a value.
There is a catch in the height notation, though. "5 feet 7 inches" is not the same as "5.7 feet". The converter takes a single number, so if you type 5.7 it works out 5.7 × 12 = 68.4 inches. But 5 feet 7 inches is 67 inches. So convert a height in feet and inches with the table below, not by typing it with a decimal point.
How does the feet to inches conversion work? Formula and example
Converting feet to inches rests on one fixed relationship: one foot is exactly 12 inches. To turn feet into inches, you multiply the number of feet by 12.
Full formula: inches = feet × 12. The other way round: feet = inches ÷ 12.
Example: you want to know how many inches 6 feet is. You substitute: 6 × 12 = 72 inches. It is the most frequently converted value, because "six feet" is a common height in English-speaking countries.
Mind the height notation. If you have 5 feet 7 inches, do not type 5.7, because the converter would work out 68.4 inches. You get the inches of a height like this: multiply the feet by 12 and add the inches. For 5 feet 7 inches that is 5 × 12 + 7 = 67 inches. Ready values are in the height table below.
