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 7989 decimeters into kilometers we have to multiply 7989 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

7989 dm → L_(km)

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

L_(km) = 7989 dm × 0.0001 km

L_(km) = 0.7989 km

The final result is:

7989 dm → 0.7989 km

We conclude that 7989 decimeters is equivalent to 0.7989 kilometers:
