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 6645 decimeters into kilometers we have to multiply 6645 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

6645 dm → L_(km)

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

L_(km) = 6645 dm × 0.0001 km

L_(km) = 0.6645 km

The final result is:

6645 dm → 0.6645 km

We conclude that 6645 decimeters is equivalent to 0.6645 kilometers:

6645 decimeters = 0.6645 kilometers
