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 8721 decimeters into kilometers we have to multiply 8721 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

8721 dm → L_(km)

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

L_(km) = 8721 dm × 0.0001 km

L_(km) = 0.8721 km

The final result is:

8721 dm → 0.8721 km

We conclude that 8721 decimeters is equivalent to 0.8721 kilometers:

8721 decimeters = 0.8721 kilometers
