Units explained

Metric / SI

Dekameter

What is a 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.

Origin of the dekameter

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.

Where it is used

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.

When and where it was developed

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1795 in France; ratified through the Metre Convention of 1875; remains a recognised SI prefix unit although informally superseded by the more common meter and hectometer in everyday surveying.

Metric / SI

Decimeter

What is a 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.

Origin of the decimeter

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").

Where it is used

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).

When and where it was developed

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:

1 dam = 100 dm
1 dm = 0.01 dam

To convert dekameters to decimeters, multiply the value in dekameters by 100. To reverse, multiply decimeters by 0.01.

How to use this converter

Type a value into the calculator. The result in decimeters updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Decimeter to Dekameter converter for the reverse direction.

Step-by-step: convert dekameters to decimeters

  1. Write down the value in dekameters (dam).
  2. Multiply that value by the factor 100.
  3. The product is the equivalent value in decimeters (dm).
  4. 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

Frequently asked questions

How many decimeters is 1 dekameter?
1 dekameter equals 100 decimeter.
How do I convert dekameters to decimeters?
Multiply the value in dekameters by 100 to get decimeters.
How do I convert decimeters back to dekameters?
Multiply the value in decimeters by 0.01, or use the Decimeter to Dekameter converter.
How many decimeters is 100 dekameters?
100 dekameters equals 10000 decimeters, because 100 × 100 = 10000.
