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 25 decimeters into kilometers we have to multiply 25 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

25 dm → L_(km)

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

L_(km) = 25 dm × 0.0001 km

L_(km) = 0.0025 km

The final result is:

25 dm → 0.0025 km

We conclude that 25 decimeters is equivalent to 0.0025 kilometers:

25 decimeters = 0.0025 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 400 × 25 decimeters.

Another way is saying that 25 decimeters is equal to 1 ÷ 400 kilometers.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twenty-five decimeters is approximately zero point zero zero three kilometers:

25 dm ≅ 0.003 km

An alternative is also that one kilometer is approximately four hundred times twenty-five decimeters.
