How to Convert to a Mixed Measurement

Usually, a measurement in feet is expressed as a measurement in feet and inches. For example, 2.25 ft. is often expressed as 2' 3". Follow these steps to convert inches to feet and inches.

Divide the total inches by 12 to find the total feet in a decimal form
32" ÷ 12 = 2.67'
If the feet measurement does not have a decimal, then you're done!
If the feet measurement does have a decimal, then subtract the decimal portion from the feet measurement to get an even feet measurement.
2.67' - .67' = 2'
Multiply the even feet measurement by 12 to find how many of the original total inches are evenly divisible by 12.
2' × 12 = 24"
Subtract the number of inches in the even foot measurement from the total inches to find the remainder. This is the inch measurement.
32" - 24" = 8"
Now, take the even feet measurement and the remainder in inches. This is the feet and inches measurement.
32" = 2' 8"
A far simpler way to get a mixed measurement is to use long division with remainders. The resulting quotient is the whole feet, and the remainder is the inches.

Our inch fraction calculator can add inches and feet together, and it also automatically converts the results to US customary, imperial, and SI metric values.

Inches and feet are both units used to measure length. Keep reading to learn more about each unit of measure.

How do you Convert Feet and Inches to Decimal Feet?

To convert feet and inches to a decimal foot value, follow a few easy steps.

Step One - multiply the foot value by 12 to convert the value to inches.

Step Two - add the feet converted to inches with the other inch value.

Step Three - divide the total inches by 12 to find the resulting value in feet as a decimal.

For example, here's how to convert 2' 8" to decimal feet using this method.

First, find the total inches.

in = (2' × 12) + 8"
in = 24" + 8"
in = 32"

Then, convert the total inches to feet.

ft = 32" ÷ 12
ft = 2.67'

What Is an Inch?

An inch is a unit of length 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.^[1]

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 is 12 inches long and is a common tool for measuring a length in inches.Another frequently used tool to perform measurements in inches is a tape measure, which commonly comes in lengths from 6' - 35'.Other types of devices used to make measurements in inches include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.

What Is a Foot?

The foot is a unit of length measurement 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.^[2]

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′.

Measurements in feet are most commonly taken 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 a measurement of length in feet.
