How Many Decimeters in a Kilometer?
There are 10,000 decimeters in 1 kilometer.
The conversions are:
1 kilometer = 1000 meters and 1 meter = 10 decimeters
So,
1 kilometer = 1000 meters = 1000 * 10 decimeters = 10,000 decimeters
Therefore, there are 10,000 decimeters in 1 kilometer.
The conversion can also be written as:
1 km = 10000 dm
Difference Between Kilometers and Decimeters
The main difference between kilometers and decimeters is that they are units of length in the metric system that differ in scale by a factor of 10,000:
- Kilometer (km): The kilometer is a unit of length equal to 1,000 meters or 100,000 centimeters. It is mainly used to measure longer distances on land.
- Decimeter (dm): The decimeter is a unit of length equal to one tenth of a meter or 10 centimeters. It is used to measure shorter distances or lengths.
Some key differences:
- Scale: 1 km = 1,000 m 1 dm = 0.1 m So 1 km is 10,000 times longer than 1 dm.
- Usage: Kilometers are used to measure longer distances like the distance between cities (e.g. 100 km). Decimeters are used for shorter lengths like the length of a pencil (e.g. 20 dm).
- Metric system: Both units are part of the metric system. Kilometers measure long distances; decimeters measure short distances.
- Conversion: To convert between them, multiply/divide by 10,000 e.g. 5 km = 50,000 dm 300 dm = 0.03 km
How to Convert Kilometers to Decimeters?
To convert kilometers to decimeters, you can use the conversion factor that defines the relationship between these two units of length. The conversion factor is based on the fact that 1 kilometer is approximately equal to 10,000 decimeters. Here’s the step-by-step process:
Conversion Formula:
Decimeters = Kilometers × 10,000
Task:
Convert 250 kilometers to decimeters.
Calculation:
Number of Decimeters = 250 × 10,000 = 25,00,000 dm
Therefore, 250 kilometers is equal to 25,00,000 decimeters.

| 800 | 8000000 |
| 900 | 9000000 |
| 1000 | 10000000 |
To convert kilometers to decimeters, you multiply the number of kilometers by 10,000 (since 1 kilometer equals 10,000 decimeters).
