How to Convert Dekameters to US Survey Feet
To convert dekameters to us survey feet, multiply the length by the following conversion ratio: 32.8083333 us survey feet/dekameter.
Since one dekameter is equal to 32.8083333 us survey feet, you can use this simple formula to convert:
The length in us survey feet is equal to the length in dekameters multiplied by 32.8083333.
For example, here's how to convert 5 dekameters to us survey feet using the formula above.
How Many US Survey Feet Are in a Dekameter?

How to Convert Dekameters 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 1968.503937 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 dekameters (dam) into fractional inches:
- Find the decimal inches result: Convert 5 dam to inches to get 1968.503937 in.
- Separate the whole inches from the decimal part: Keep the whole number 1968 aside, leaving the decimal remainder 0.503937.
- Multiply the decimal part by your desired fraction denominator (16, 32, or 64) and round half up: Multiply 0.503937 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 Dekameter?
A dekameter is a unit of length equal to 10 meters (m), the base unit for length. Metric unit equal to 10 meters. [1]
The dekameter is classified as a metric and SI-compatible unit of length. Dekameters can be abbreviated as dam; for example, 1 dekameter can be written as 1 dam.
In the metric system, "deka" is the standard SI prefix for tens, or 10¹. This makes the dekameter (dam) a convenient decimal multiple of the meter (m).
In practice, dekameters (dam) are widely used across standard length applications within SI metric workflows, engineering documentation, and technical data sheets.
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). [2]
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.
When converting length between dekameters (dam) and us survey feet (ft (US)), keep full floating-point precision (1 dam = 32.8083333 ft (US); 1 ft (US) = 0.0304801 dam) during intermediate calculations and round only the final us survey foot figure to match your instrument tolerance.
