To convert a foot measurement to an inch measurement, multiply the length by the conversion ratio.
Since one foot is equal to 12 inches, you can use this simple formula to convert:
How Many Inches are in a Foot?
There are 12 inches in a foot, which is why we use this value in the formula above.
1' = 12″
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 and inches are both units used to measure length. Keep reading to learn more about each unit of measure.
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.<1>
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 known as a prime, though a single-quote (') is often used instead of the prime symbol for convenience. Using the prime symbol, 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 are simply the measurement of length in feet.

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.<2>
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 known as a double-prime. Often a double-quote (“) is used instead of a double-prime for convenience. A double-prime is commonly used to express 1 in as 1″.

The standard ruler has 12″, and is 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.
We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.
