Units & Standards

What Is a Yard and What Is a Dekameter?

The yard (yd) is an imperial and US customary unit of length equal to 3 feet or 36 inches. Standardized by the 1959 International Yard Agreement, 1 yard is legally defined as exactly 0.9144 meters.

The dekameter (dam) (sometimes written decameter or dkm) is an SI decimal multiple of the meter, defined as exactly 10 meters (or 32.8084 feet / 10.9361 yards).

Because 1 yard equals 0.9144 meters and 1 dekameter equals 10 meters, the conversion is exact: 1 yard = 0.9144 ÷ 10 = 0.09144 dekameters.

Frequently Asked Questions: Yard to Dekameter

How many dekameters are in 1 yard?
There are exactly 0.09144 dekameters (dam) in 1 yard. This exact value comes from the 1959 International Yard Agreement defining 1 yard as exactly 0.9144 meters. Since 1 dekameter equals 10 meters, 1 yard equals 0.9144 ÷ 10 = 0.09144 dam.
What is the formula to convert yards to dekameters?
To convert yards to dekameters, multiply the yard measurement by 0.09144 (or convert to meters by multiplying by 0.9144, then divide by 10). Formula: Dekameters (dam) = Yards (yd) × 0.09144. Example: 100 yards × 0.09144 = 9.144 dam.
How do I convert dekameters back to yards?
To convert dekameters to yards, divide the dekameter value by 0.09144, or multiply by approximately 10.93613. Formula: Yards (yd) = Dekameters (dam) ÷ 0.09144. Example: 5 dam × 10.93613 = 54.68 yards (length of a 50m Olympic pool).
What is the abbreviation or symbol for a dekameter?
The official SI symbol for dekameter is 'dam' (and occasionally 'dkm' in legacy contexts). It combines the SI prefix 'deka-' (10) with the base unit 'meter' (m). Do not confuse it with 'dm', which is decimeter (0.1 meter).
How many yards are in 1 dekameter?
1 dekameter equals exactly 10 meters, which is approximately 10.93613 yards (or 32.8084 feet / 393.701 inches).
Why do meteorologists use dekameters?
Meteorologists use dekameters (dam) on upper-air constant pressure weather maps (such as 500-hPa and 300-hPa charts) to express geopotential heights as convenient 3-digit numbers (e.g. 570 dam instead of 5,700 meters).
