Units explained
Dekameter
A dekameter (also spelled decameter) is a metric unit of length equal to ten meters (10 m). It is one of the less commonly used SI prefix units and primarily appears in agricultural, surveying, and atmospheric contexts.
The dekameter was defined alongside the meter when France adopted the metric system in 1795, using the standard SI prefix deca- (from Greek deka, ten) to denote a multiplication by ten.
Dekameters are used in some European agricultural contexts (parcel sizes, field measurements), atmospheric science (cloud heights), and certain track and field events. Modern usage is uncommon outside specialised technical fields.
Adopted in 1795 in France; ratified through the Metre Convention of 1875; remains a recognised SI prefix unit although informally superseded by the more common meter and hectometer in everyday surveying.
Decimeter
A decimeter is a metric unit of length equal to one tenth of a meter (1/10 m). Though uncommon in English-speaking countries, it remains a standard SI unit and is used in some scientific and educational contexts.
Like the centimeter and millimeter, the decimeter was defined when France adopted the metric system in 1795, using the SI prefix deci- (from Latin decimus, "tenth").
Decimeters are rarely used in everyday measurement in English-speaking countries but appear in some European technical specifications and in volume conversions (1 cubic decimeter = 1 liter).
Defined in 1795 as part of the original French metric system; remains a recognized SI unit though uncommonly used in commerce.
Dekameter to Decimeter conversion formula
The relationship between dekameters and decimeters:
To convert dekameters to decimeters, multiply the value in dekameters by 100. To reverse, multiply decimeters by 0.01.

Step-by-step: convert dekameters to decimeters
- Write down the value in dekameters (dam).
- Multiply that value by the factor 100.
- The product is the equivalent value in decimeters (dm).
- To reverse, multiply the decimeter value by 0.01.
Worked examples
Example 1 — Convert 1 dam to dm:
1 × 100 = 100 dm
Example 2 — Convert 100 dam to dm:
100 × 100 = 10000 dm
