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 3971 decimeters into kilometers we have to multiply 3971 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

3971 dm → L_(km)

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

L_(km) = 3971 dm × 0.0001 km

L_(km) = 0.3971 km

The final result is:

3971 dm → 0.3971 km

We conclude that 3971 decimeters is equivalent to 0.3971 kilometers:

3971 decimeters = 0.3971 kilometers
