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 250 decimeters into kilometers we have to multiply 250 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

250 dm → L_(km)

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

L_(km) = 250 dm × 0.0001 km

L_(km) = 0.025 km

The final result is:

250 dm → 0.025 km

We conclude that 250 decimeters is equivalent to 0.025 kilometers:

250 decimeters = 0.025 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 40 × 250 decimeters.

Another way is saying that 250 decimeters is equal to 1 ÷ 40 kilometers.

Approximate result

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

250 dm ≅ 0.025 km

An alternative is also that one kilometer is approximately forty times two hundred fifty decimeters.
