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1795 in France; ratified through the Metre Convention of 1875; remains a recognised SI prefix unit although informally superseded by the more common meter and hectometer in everyday surveying.
Micrometer
A micrometer (also called a micron) is a metric unit of length equal to one millionth of a meter (1×10⁻⁶ m). It is the standard unit for measuring microscopic dimensions in biology, materials science, and semiconductor manufacturing.
Defined alongside the meter when France adopted the metric system in 1795, using the SI prefix micro- (from Greek mikros, "small") to denote one-millionth.
Micrometers are used to measure cell sizes, bacteria, semiconductor process nodes, fiber diameters, dust particles, and wavelengths of infrared radiation. The diameter of a human hair is about 70 μm.
Defined in 1795 as part of the original French metric system; the name "micron" was officially deprecated by the BIPM in 1967 in favor of micrometer.
Dekameter to Micrometer conversion formula
The relationship between dekameters and micrometers:
To convert dekameters to micrometers, multiply the value in dekameters by 1e+7. To reverse, multiply micrometers by 1e-7.

Step-by-step: convert dekameters to micrometers
- Write down the value in dekameters (dam).
- Multiply that value by the factor 1e+7.
- The product is the equivalent value in micrometers (μm).
- To reverse, multiply the micrometer value by 1e-7.
Worked examples
Example 1 — Convert 1 dam to μm:
1 × 1e+7 = 1e+7 μm
Example 2 — Convert 100 dam to μm:
100 × 1e+7 = 1e+9 μm
