Conversion formula

The conversion factor from decimeters to kilometers is 0.0001, which means that 1 decimeter is equal to 0.0001 kilometers:

1 dm = 0.0001 km

To convert 10000 decimeters into kilometers we have to multiply 10000 by the conversion factor in order to get the length amount from decimeters to kilometers. We can also form a simple proportion to calculate the result:

1 dm → 0.0001 km

10000 dm → L_(km)

Solve the above proportion to obtain the length L in kilometers:

L_(km) = 10000 dm × 0.0001 km

L_(km) = 1 km

The final result is:

10000 dm → 1 km

We conclude that 10000 decimeters is equivalent to 1 kilometers:

10000 decimeters = 1 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 1 × 10000 decimeters.

Another way is saying that 10000 decimeters is equal to 1 ÷ 1 kilometers.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that ten thousand decimeters is approximately one kilometers:

10000 dm ≅ 1 km

An alternative is also that one kilometer is approximately one times ten thousand decimeters.
