How to Convert Inches to Feet
To convert inches to feet, multiply the length by the following conversion ratio: 0.0833333 feet/inch.
Since one inch is equal to 0.0833333 feet, you can use this simple formula to convert:
The length in feet is equal to the length in inches multiplied by 0.0833333.
For example, here's how to convert 60 inches to feet using the formula above.

How to Convert Inches to Fractional Inches (1/16″, 1/32″ & 1/64″)
Plain-language method for turning decimal inches into a standard tape-measure or machinist ruler fraction
Calculators give you a decimal number (such as 60 in), but tape measures and woodworking rulers are marked in binary fractions of an inch—most commonly 1/16″ on carpenter tapes, 1/32″ on fine woodworking rules, and 1/64″ on machinist scales.
Here is the step-by-step worked example for converting 60 inches (in) into fractional inches:
- Find the decimal inches result: Convert 60 in to inches to get 60 in.
- Separate the whole inches from the decimal part: Keep the whole number 60 aside, leaving the decimal remainder 0.
- Multiply the decimal part by your desired fraction denominator (16, 32, or 64) and round half up: Multiply 0 by 16, 32, or 64, then round to the nearest whole number (values ending in .5 round up).
- Reduce the fraction to lowest terms: If the rounded top number (numerator) is even, divide both top and bottom by 2 (or their Greatest Common Divisor) until the top number is odd, then combine with your whole inches.
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 as exactly 0.9144 meters under the 1959 International Yard and Pound Agreement, one inch equals exactly 2.54 centimeters (25.4 millimeters or 25,400,000 nanometers). [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' to 35'. Other devices used to measure in inches include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.
What Is a Foot?
A foot is a US customary and imperial unit of length equal to 12 inches or 1/3 of a yard. Under the 1959 International Yard and Pound Agreement, one foot is legally defined as exactly 0.3048 meters (30.48 centimeters). [2]
Feet are widely used in the United States, Canada, and the United Kingdom for human height, building construction, real estate floor plans, and aviation altitude. Feet can be abbreviated as ft; for example, 1 foot can be written as 1 ft.
Feet can also be denoted using the ′ symbol, known as a prime (or a single quote ' for convenience). For example, 5 feet 10 inches is frequently written as 5′ 10″ or 5' 10".
Feet are measured using 12-inch rulers, carpenter's folding rules, 25-foot steel tape measures, and laser distance meters across residential framing, architecture, and surveying.
When converting length between inches (in) and feet (ft), keep full floating-point precision (1" = 0.0833333 ft; 1 ft = 12 in) during intermediate calculations and round only the final foot figure to match your instrument tolerance.
