How do you convert kilometers to dekameters?

To convert kilometers (km) to dekameters (dam), multiply the length in kilometers by 100 (dekameters = kilometers × 100).

What is 5 kilometers in dekameters?

5 kilometers (5 km) is equal to 500 dekameters (500 dam).

Which is larger, 1 kilometer (km) or 1 dekameter (decameter) (dam)?

One kilometer (km) is larger than one dekameter (decameter) (dam). Specifically, 1 km contains 100 dam, whereas 1 dam is 0.01 km.

How do I convert back from dekameters (dam) to kilometers (km)?

To reverse the calculation from dam to km, multiply your dekameter (decameter) value by the inverse factor 0.01 (or divide by 100). You can also click the Swap button in the tool above to flip directions in one click.

How many decimal places should I round km to dam results to?

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 5 km ≈ 500.00 dam). For engineering, laboratory, or machining specifications, select 4 or 6 decimals—or Scientific (10ⁿ) mode—in the calculator toolbar above.

How to Convert Kilometers to Dekameters

To convert kilometers to dekameters, multiply the length by the following conversion ratio: 100 dekameters/kilometer.

Since one kilometer is equal to 100 dekameters, you can use this simple formula to convert:

dekameters = kilometers × 100

The length in dekameters is equal to the length in kilometers multiplied by 100.

For example, here's how to convert 5 kilometers to dekameters using the formula above.

dekameters = (5 km × 100) = 500 dam

How Many Dekameters Are in a Kilometer?

There are 100 dekameters in a kilometer, which is why we use this value in the formula above.

1 km = 100 dam|1 dam = 0.01 km

Our kilometer fraction and decimal calculator can convert kilometers and dekameters, and it automatically converts the results to US customary, imperial, and SI metric values.

Kilometers and dekameters are both units used to measure length. Keep reading to learn more about each unit.

What Is a Kilometer?

A kilometer is a unit of length equal to 1,000 meters (m), the base unit for length. Metric unit equal to 1,000 meters. [1]

The kilometer is classified as an International System of Units (SI) unit of length. Kilometers can be abbreviated as km; for example, 1 kilometer can be written as 1 km.

In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilometer (km) a convenient decimal multiple of the meter (m).

In practice, kilometers (km) are widely used across large-scale industrial, bulk, and macro-level length specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.

What Is a Dekameter?

A dekameter is a unit of length equal to 10 meters (m), the base unit for length. Metric unit equal to 10 meters. [2]

The dekameter is classified as a metric and SI-compatible unit of length. Dekameters can be abbreviated as dam; for example, 1 dekameter can be written as 1 dam.

In the metric system, "deka" is the standard SI prefix for tens, or 10¹. This makes the dekameter (dam) a convenient decimal multiple of the meter (m).

In practice, dekameters (dam) are widely used across standard length applications within SI metric workflows, engineering documentation, and technical data sheets.

Learn more about dekameters in our Length Converter.

When converting length between kilometers (km) and dekameters (dam), keep full floating-point precision (1 km = 100 dam; 1 dam = 0.01 km) during intermediate calculations and round only the final dekameter figure to match your instrument tolerance.
