Inches To Feet Converter

1. Leave Direction on Inches to feet. Type the inches as a whole number, a decimal such as 70.5, or a fraction such as 70 1/2 with a space before the fraction.
2. Pick how to round feet and inches. Choose 1/16 inch for a tape measure, 1/2 inch for a room sketch, or decimal inches for a spreadsheet.
3. Read the decimal feet and the feet and inches together. The verdict tells you whether the feet and inches are exact or rounded, and by how much.

Here is what each result means:

An inches to feet conversion regroups a length into 12-inch units. It does not change the length itself, only the way you write it. A foot is exactly 12 inches, and a yard is exactly 3 feet, or 36 inches.

Both units belong to the US customary system and the British imperial system. NIST Handbook 44 lists 12 inches = 1 foot as the first line of its US length table. UK law sets the same link another way: the foot is 1/3 yard and the inch is 1/36 yard.

The answer has two common forms. Decimal feet, like 5.8333 ft, suit calculators, spreadsheets and area formulas. Feet and inches, like 5 ft 10 in, suit tape measures, height charts and floor plans. This converter gives both at once, so you do not have to turn 0.8333 ft back into 10 in by hand.

For smaller parts, the inches to mm converter is the better fit, since millimeters avoid fractions.

The converter divides your inches by 12. The quotient is decimal feet. The whole part of that quotient is the feet, and the leftover inches are the remainder after taking 12 inches for each foot.

1. Turn any fraction into a decimal. 150 1/2 in becomes 150.5 in.
2. Divide by 12. 150.5 / 12 = 12.541667 ft.
3. Take the whole feet, 12, and the leftover inches: 150.5 - 144 = 6.5 in. The answer is 12 ft 6 1/2 in.
4. Round the leftover inches to your tape. The tool rounds to the nearest 1/16, 1/8, 1/4 or 1/2 inch, and reduces the fraction, so 8/16 shows as 1/2.

Because 12 is not a power of 10, 1 in = 0.083333 ft never ends. That is why decimal feet are shown to 7 figures, while the feet and inches form can be exact.

Height. 70 in / 12 = 5.8333 ft. The whole feet are 5, and 70 - 60 = 10 in is left over, so the height is 5 ft 10 in. A height of 64 in is 5 ft 4 in.

Room size. A wall that measures 150 1/2 in is 12 ft 6 1/2 in, or 12.5417 ft. A second wall of 138 in is 11 ft 6 in. The floor area is 150.5 x 138 / 144 = 144.23 sq ft, because 144 square inches make 1 square foot. The tile flooring calculator takes those feet straight in.

TV screen. A 55 in TV is measured on the diagonal, so 55 / 12 = 4.58 ft corner to corner. For a 16:9 screen, the width is about 47.9 in, or 3 ft 11 7/8 in, and the height is about 27 in.

Fraction of an inch. A shelf board of 35 3/8 in is 35.375 / 12 = 2.9479 ft, or 2 ft 11 3/8 in.

Reverse. Switch the direction and 5.5 ft x 12 = 66 in. Remember that 5.5 ft is 5 ft 6 in, not 5 ft 5 in.

The 12-to-1 link is fixed, so the answer only moves with how you enter the inches and how you round the leftover part.

Fraction Rounding

A 1/16 inch step is 0.0625 in, or about 1.6 mm. Rounding to 1/2 inch can move a cut by up to 1/4 inch. Pick the step your tape or saw can hold.

Decimal Feet Versus Feet and Inches

0.5 ft is 6 in, and 0.1 ft is only 1.2 in. Surveyors and some plans use decimal feet (tenths and hundredths of a foot), while carpenters use feet, inches and fractions.

Diagonal Versus Width

Screen sizes are diagonal. Converting 55 in to 4.58 ft tells you the corner-to-corner size, not the width that has to fit a wall or cabinet.

Measurement Accuracy

A tape read to the nearest 1/8 inch cannot give a result truer than 1/16 inch either way. The converter keeps your input as typed and does not add precision you did not measure.

Here are common 16:9 screen sizes with width and height worked out from the diagonal. The math is width = diagonal x 16 / 18.358 and height = diagonal x 9 / 18.358, where 18.358 is the square root of 16 squared plus 9 squared.

Leave a little extra room for the frame, which the diagonal does not include. For ultrawide or 4:3 screens, measure the width and height directly and convert each one.

Rooms, Floors and Walls

Tape measures give long walls in inches, but flooring, paint and rugs are sold by the foot or square foot. Convert each wall to feet first. The guide on how to calculate square footage of a house covers the next step.

Heights and Growth Charts

Doctor visits and sports rosters list height in inches, while people talk in feet and inches. 74 in becomes 6 ft 2 in at once.

Shopping for Screens, Furniture and Fabric

Product pages mix inches and feet. Converting 96 in to 8 ft, or a 75 in TV to 6.25 ft diagonal, makes it easy to compare against the space you have. For fabric sold by the yard, the yards to feet converter handles the next step.

Every value below comes from dividing by 12. Decimal feet are rounded to 4 places.

Use the rows as building blocks: 1 in is 0.0833 ft, 6 in is 0.5 ft and 9 in is 0.75 ft, so 69 in is 5 ft plus 9 in, or 5.75 ft.

1. Reading Decimal Feet as Feet and Inches

5.83 ft is not 5 ft 83 in or 5 ft 8.3 in. The .83 is a share of a foot, so it is 0.83 x 12 = 10 in.

2. Dividing by 10 Instead of 12

70 in / 10 = 7 is 20 percent too high. Inches group in twelves, not tens.

3. Converting Square Inches with the Length Factor

One square foot is 144 square inches, not 12. Divide an area in square inches by 144.

4. Dropping the Fraction

A 35 3/8 in board cut as 35 in is 3/8 in short. Keep the fraction until the final cut.

5. Treating a Screen Size as the Width

A 65 in TV is only about 56.7 in wide. Measure the wall against the width, not the diagonal.

6. Writing 5 1/2 Ft as 5 Ft 5 In

Half a foot is 6 in. Always multiply the decimal part by 12.

The conversion is exact, because a foot is defined as 12 inches. Any error comes from the measurement you type or the fraction step you choose.

There are exactly 12 inches in 1 foot. NIST Handbook 44 lists this as the base of the US length table, and UK law gives the same link through the yard.

Divide by 12 and keep the remainder. For 83 in: 83 / 12 = 6 with 11 left over, so the answer is 6 ft 11 in.

Sixty-eight inches is 5 ft 8 in, or 5.667 ft. That is 172.72 cm.

One sixteenth of an inch is 0.0052083 ft. It is 1.5875 mm, the smallest mark on most US tape measures.

A 65 in TV is 5.42 ft on the diagonal. For a 16:9 screen, the width is about 56.7 in (4.72 ft) and the height about 31.9 in.

Multiply by 12: 0.75 x 12 = 9 in. So 5.75 ft is 5 ft 9 in.

Yes. Put a space between the whole number and the fraction. The tool also accepts a fraction on its own, such as 3/8, and plain decimals.

Count dozens. Take off 12 in for each foot until less than 12 is left. For 100 in: 8 dozens is 96, so 8 ft 4 in.

Exactly 1 square foot, because 12 x 12 = 144. Divide any area in square inches by 144, not by 12.

A calculator shows decimal feet, such as 5.8333. This tool also shows feet and inches, 5 ft 10 in. They are the same length written two ways.

• US customary length table: 12 inches = 1 foot, 3 feet = 1 yard (NIST Handbook 44, 2026, Appendix C).
• Exact factor: inch to centimeter, 2.54 (NIST SP 811, Appendix B.8).
• Unit conversion, significant digits and rounding guidance (NIST Office of Weights and Measures).
• UK definitions: foot = 1/3 yard, inch = 1/36 yard (Weights and Measures Act 1985, Schedule 1, legislation.gov.uk).
