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 8490 decimeters into kilometers we have to multiply 8490 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

8490 dm → L_(km)

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

L_(km) = 8490 dm × 0.0001 km

L_(km) = 0.849 km

The final result is:

8490 dm → 0.849 km

We conclude that 8490 decimeters is equivalent to 0.849 kilometers:

8490 decimeters = 0.849 kilometers
