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 6378 decimeters into kilometers we have to multiply 6378 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

6378 dm → L_(km)

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

L_(km) = 6378 dm × 0.0001 km

L_(km) = 0.6378 km

The final result is:

6378 dm → 0.6378 km

We conclude that 6378 decimeters is equivalent to 0.6378 kilometers:

6378 decimeters = 0.6378 kilometers
