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1795 in France; ratified through the Metre Convention of 1875; remains a recognised SI prefix unit although informally superseded by the more common meter and hectometer in everyday surveying.
Hectometer
A hectometer is a metric unit of length equal to one hundred meters (100 m). It is occasionally used in sports, agricultural surveying, and some European real-estate contexts.
The hectometer was defined alongside the meter when France adopted the metric system in 1795, using the SI prefix hecto- (from Greek hekaton, hundred) to denote multiplication by 100.
Hectometers appear in some sports contexts (the 100 m sprint is technically 1 hm), in agriculture (parcel sizes in some European nations), and in atmospheric science. Most contexts now use meters or kilometers instead.
Adopted in 1795 in France; ratified through the Metre Convention of 1875; remains a defined SI prefix unit although rarely used outside specialised contexts.
Dekameter to Hectometer conversion formula
The relationship between dekameters and hectometers:
To convert dekameters to hectometers, multiply the value in dekameters by 0.1. To reverse, multiply hectometers by 10.

Step-by-step: convert dekameters to hectometers
- Write down the value in dekameters (dam).
- Multiply that value by the factor 0.1.
- The product is the equivalent value in hectometers (hm).
- To reverse, multiply the hectometer value by 10.
Worked examples
Example 1 — Convert 1 dam to hm:
1 × 0.1 = 0.1 hm
Example 2 — Convert 100 dam to hm:
100 × 0.1 = 10 hm
