Inches to Feet Converter

Common questions

How many feet is 1 inch?

One twelfth of a foot, which the converter prints as 0.0833333333333 ft. A foot is exactly twelve inches, so the division itself is exact and only the printed decimal repeats. Inch counts that are a multiple of twelve come back clean: 12 in reads 1, 36 in reads 3 and 144 in reads 12. Going the other way, 1 ft is 12 in and half a foot is 6 in.

How do I read a decimal foot as feet and inches?

Keep the whole number of feet and multiply the part after the point by 12. The converter prints 70 in as 5.83333333333 ft, which is 5 whole feet plus 0.83333333333 of a foot, and that fraction times 12 is 10, so 5 ft 10 in. The quarter marks are worth knowing by heart: 0.25 ft is 3 in, 0.5 ft is 6 in and 0.75 ft is 9 in. The headline stays in decimal feet because that is the number a spreadsheet or a cut list wants; the chart at the foot of this page prints both forms together.

What is 66 inches in feet?

5.5 ft, which is 5 ft 6 in. Twelve goes into 66 five times with 6 left over, so that is 5 whole feet and 6 inches, and those 6 inches are half a foot. The list under the answer shows the same length as 167.64 cm and 1.6764 m, both exact, because an inch is exactly 2.54 centimetres.

How do I convert feet back to inches?

Press the Swap units button between the two boxes and the pair reverses without reloading the page: type 5.5 and the answer is 66 in, and 6 reads 72 in. By hand it is the same arithmetic the other way round, a multiplication by 12. Both unit menus stay open as well, so the same measurement will go from inches to millimetres, metres, yards or miles without leaving this page, and the Uncommon units switch adds seven more, from nanometres and thous to light years and parsecs.

Why does the answer run to so many decimal places?

Because most inch counts do not divide evenly by twelve: 1 in is 0.08333... ft and the digits repeat without end. Results are shown to twelve significant digits with trailing zeros dropped, so the exact cases stay clean, 12 in reads 1 rather than 0.99999, and everything else keeps enough precision for you to round wherever you want. Copy result puts the headline on your clipboard exactly as printed, without the thousands separators.

Why does this page open on inches and feet when I last converted something else?

Because a page that names a pair should show that pair. This one sets inches and feet on arrival, ahead of whatever the converter last remembered, and it leaves the main unit converter's own memory alone: go back there and it is still on the pair you left it on. The number you last typed does travel with you, since it is usually the one you are still working on. Nothing is uploaded either way. The conversion is arithmetic against a table of factors that ships with the page, so it keeps working with no network connection once the page has loaded.
