## Conversion formula

The conversion factor from kilometers to decimeters is 10000, which means that 1 kilometer is equal to 10000 decimeters:

1 km = 10000 dm

To convert 25 kilometers into decimeters we have to multiply 25 by the conversion factor in order to get the length amount from kilometers to decimeters. We can also form a simple proportion to calculate the result:

1 km → 10000 dm

25 km → L(dm)

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

L(dm) = 25 km × 10000 dm

L(dm) = 250000 dm

The final result is:

25 km → 250000 dm

We conclude that 25 kilometers is equivalent to 250000 decimeters:

25 kilometers = 250000 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 4.0E-6 × 25 kilometers.

Another way is saying that 25 kilometers is equal to 1 ÷ 4.0E-6 decimeters.

## Approximate result

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

25 km ≅ 250000 dm

An alternative is also that one decimeter is approximately zero times twenty-five kilometers.
