Introduction

This inches to feet calculator turns any inch measurement into feet in one step. Type a number like 20, a decimal like 5.5, or a fraction like 5 1/4, and you get the answer right away.

You get two answers at once. The first is decimal feet, such as 1.6667 ft. The second is feet and inches, such as 1 ft 8 in. Decimal feet work well for math and spreadsheets. Feet and inches work well for building, sewing, and everyday jobs.

The math is simple: divide the inches by 12, because 12 inches make 1 foot. The calculator shows each step, so you can check the work or learn how to do it yourself. A bar chart shows how much of your length is whole feet and how many inches are left over.

You can copy either answer with one click. A quick table below lists common conversions, from 1 inch up to 240 inches, so you can find answers fast without typing.

Inches to Feet: What It Means

An inch and a foot are both units of length in the US customary and imperial systems. 1 foot equals 12 inches. So to change inches into feet, you divide the number of inches by 12.

The Formula

Feet = Inches ÷ 12

Example: 30 inches ÷ 12 = 2.5 feet.

Two Ways to Show the Answer

There are two common ways to write the same length:

  • Decimal feet, one number with a decimal, like 2.5 ft. Builders, engineers, and spreadsheets often use this form.
  • Feet and inches, whole feet plus the leftover inches, like 2 ft 6 in. People use this form for height, lumber, and room sizes.

To get feet and inches, keep the whole number of feet, then multiply it by 12 and subtract that from your starting inches. What is left over is the extra inches.

Quick Numbers to Remember

  • 6 inches = 0.5 ft
  • 12 inches = 1 ft
  • 18 inches = 1.5 ft (1 ft 6 in)
  • 36 inches = 3 ft (1 yard)
  • 72 inches = 6 ft

Working With Fractions

Tape measures use fractions like 1/2, 1/4, and 1/8 of an inch. Change the fraction to a decimal first, then divide by 12. For example, 5 1/4 inches becomes 5.25 inches, and 5.25 ÷ 12 = 0.4375 ft.

Where You Use This

Converting inches to feet helps with home projects, cutting wood, buying carpet or flooring, measuring a person's height, hanging TVs and shelves, and reading blueprints. Many plans list sizes in feet, but rulers and tape measures show inches, so switching between them is a daily task.

Related Units

Once you have feet, other units are easy. There are 3 feet in 1 yard, and 1 foot equals 30.48 centimeters (0.3048 meters). One inch equals 2.54 centimeters.

Frequently asked questions

How many inches are in a foot?

There are exactly 12 inches in 1 foot. This is a fixed number, not a rounded one. That is why you divide inches by 12 to get feet, and multiply feet by 12 to get inches.

How do you convert inches to feet in your head?

Count how many times 12 fits into your number, then keep what is left over.

  • 100 inches: 12 × 8 = 96, with 4 left over, so 8 ft 4 in.
  • 50 inches: 12 × 4 = 48, with 2 left over, so 4 ft 2 in.

For decimal feet, divide the leftover inches by 12. So 4 in ÷ 12 = 0.33 ft.

How many feet is 60 inches?

60 inches is 5 feet exactly, because 12 × 5 = 60. There are no leftover inches. A person who is 60 inches tall is 5 feet 0 inches tall.

How many feet is 72 inches?

72 inches is 6 feet, since 12 × 6 = 72. Other easy ones: 84 inches is 7 feet, 96 inches is 8 feet, and 120 inches is 10 feet.

What is 100 inches in feet?

100 ÷ 12 = 8.3333 feet, which is the same as 8 feet 4 inches. The 0.3333 part of a foot equals 4 inches (0.3333 × 12 = 4).

How do you change a height like 5'7" into inches?

Multiply the feet by 12, then add the extra inches.

5 × 12 = 60, and 60 + 7 = 67 inches.

To go back, divide 67 by 12 to get 5.58 feet, which is 5 feet with 7 inches left over.

What does 0.5 feet mean in inches?

0.5 feet is 6 inches, or half a foot. Here are other common decimals:

  • 0.25 ft = 3 in
  • 0.75 ft = 9 in
  • 0.1 ft = 1.2 in
  • 0.33 ft = about 4 in

To turn any decimal foot into inches, multiply it by 12.

How do you convert tape measure fractions like 3/4 inch into feet?

First turn the fraction into a decimal, then divide by 12.

  • 3/4 in = 0.75 in, and 0.75 ÷ 12 = 0.0625 ft
  • 1/2 in = 0.5 in = 0.0417 ft
  • 1/8 in = 0.125 in = 0.0104 ft

For a mixed number like 5 1/4, use 5.25 inches, which is 0.4375 ft.

Why do builders write measurements in decimal feet?

Decimal feet are easier to add, subtract, and put into a spreadsheet or estimate. You cannot type 8 ft 4 in into a math formula, but you can type 8.3333. Carpenters still cut with feet and inches, so plans often show both.

How do you add feet and inches together?

Add the feet, then add the inches. If the inches add up to 12 or more, trade every 12 inches for 1 foot.

Example: 3 ft 8 in + 2 ft 7 in = 5 ft 15 in. Since 15 in is 1 ft 3 in, the answer is 6 ft 3 in.

What is the symbol for feet and inches?

One mark (') means feet and two marks (") mean inches. So 5'10" reads as 5 feet 10 inches. You may also see 5 ft 10 in or 5-10.

How many inches are in a yard and in a meter?

A yard is 3 feet, or 36 inches. A meter is about 39.37 inches, which is 3 feet 3.37 inches. One inch equals 2.54 centimeters, and one foot equals 30.48 centimeters.

What is the difference between a linear foot and a square foot?

A linear foot measures length in one direction only, like 12 inches of trim or pipe. A square foot measures area, and it equals a square 12 inches by 12 inches, or 144 square inches. Flooring and carpet are sold by square foot, while lumber and trim are sold by linear foot.

How do you convert inches to feet in Excel?

Type =A1/12 to get decimal feet from inches in cell A1. For whole feet and leftover inches, use =INT(A1/12) for the feet and =MOD(A1,12) for the inches.
