How to Convert US Survey Feet to Feet
To convert us survey feet to feet, multiply the length by the following conversion ratio: 1.000002 feet/us survey foot.
Since one us survey foot is equal to 1.000002 feet, you can use this simple formula to convert:
The length in feet is equal to the length in us survey feet multiplied by 1.000002.
For example, here's how to convert 5 us survey feet to feet using the formula above.
How Many Feet Are in a US Survey Foot?
There are 1.000002 feet in a us survey foot, which is why we use this value in the formula above.
Our us survey foot fraction and decimal calculator can convert us survey feet and feet, and it automatically converts the results to US customary, imperial, and SI metric values.
US Survey Feet and feet are both units used to measure length. Keep reading to learn more about each unit.
How to Convert US Survey Feet 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 60.00012 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 5 us survey feet (ft (US)) into fractional inches:
- Find the decimal inches result: Convert 5 ft (US) to inches to get 60.00012 in.
- Separate the whole inches from the decimal part: Keep the whole number 60 aside, leaving the decimal remainder 0.00012.
- Multiply the decimal part by your desired fraction denominator (16, 32, or 64) and round half up: Multiply 0.00012 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 a US Survey Foot?
A us survey foot is a unit of length equal to 0.3048006 meters (m), the base unit for length. Geodetic US Survey foot defined as 1200/3937 meters (approx. 0.30480061 m). [1]
The us survey foot is classified as a US customary unit of length. US Survey Feet can be abbreviated as ft (US); for example, 1 us survey foot can be written as 1 ft (US).
When working with us survey feet (ft (US)) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, us survey feet (ft (US)) are widely used across standard length applications within US customary workflows, engineering documentation, and technical data sheets.
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 us survey feet (ft (US)) and feet (ft), keep full floating-point precision (1 ft (US) = 1.000002 ft; 1 ft = 0.999998 ft (US)) during intermediate calculations and round only the final foot figure to match your instrument tolerance.
