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.
