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 500 decimeters into kilometers we have to multiply 500 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

500 dm → L_(km)

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

L_(km) = 500 dm × 0.0001 km

L_(km) = 0.05 km

The final result is:

500 dm → 0.05 km

We conclude that 500 decimeters is equivalent to 0.05 kilometers:

500 decimeters = 0.05 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 20 × 500 decimeters.

Another way is saying that 500 decimeters is equal to 1 ÷ 20 kilometers.

Approximate result

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

500 dm ≅ 0.05 km

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