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 2509 decimeters into kilometers we have to multiply 2509 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

2509 dm → L_(km)

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

L_(km) = 2509 dm × 0.0001 km

L_(km) = 0.2509 km

The final result is:

2509 dm → 0.2509 km

We conclude that 2509 decimeters is equivalent to 0.2509 kilometers:

2509 decimeters = 0.2509 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 3.9856516540454 × 2509 decimeters.

Another way is saying that 2509 decimeters is equal to 1 ÷ 3.9856516540454 kilometers.

Approximate result

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

2509 dm ≅ 0.251 km

An alternative is also that one kilometer is approximately three point nine eight six times two thousand five hundred nine decimeters.
