## How to Convert Feet to Inches To convert a foot measurement to an inch measurement, multiply the length by the conversion ratio. One foot is equal to 12 inches, so use this simple formula to convert:

inches = feet × 12

The length in inches is equal to the feet multiplied by 12.

For example, here's how to convert 5 feet to inches using the formula above.
5' = (5 × 12) = 60" Our inch fraction calculator can add feet and inches together and it also automatically converts the results to US customary, imperial and SI metric values.

## Feet

The foot is a unit of linear length measure equal to 12 inches or 1/3 of a yard. Because the international yard is legally defined to be equal to exactly 0.9144 meters, one foot is equal to 0.3048 meters.

The foot is a US customary and imperial unit of length. Feet can be abbreviated as ft, for example 1 foot can be written as 1 ft.

Feet can also be denoted using the symbol, otherwise know as a prime, though a single-quote (') is often used instead of the prime symbol for convenience. Using the prime, 1 ft can be written as 1′.

The foot is most commonly measured using either a standard 12" ruler or a tape measure, though there are many other measuring devices available.. Feet are sometimes referred to as linear feet, which is simply the value of a length in feet, learn more.

## Inches

An inch is a unit of linear length measure equal to 1/12 of a foot or 1/36 of a yard. Because the international yard is legally defined to be equal to exactly 0.9144 meters, one inch is equal to 2.54 centimeters.

The inch is a US customary and imperial unit of length. Inches can be abbreviated as in, for example 1 inch can be written as 1 in.

Inches can also be denoted using the symbol, otherwise know as a double-prime. Often a double-quote (") is used instead of a double-prime for convenience. Using the double-prime, 1 in can be written as 1″. The standard ruler has 12", and are a common measuring tool for measuring inches. They are also often measured using tape measures which commonly come in lengths from 6' - 35'. Other types of measuring devices include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.
