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 3972 decimeters into kilometers we have to multiply 3972 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

3972 dm → L_(km)

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

L_(km) = 3972 dm × 0.0001 km

L_(km) = 0.3972 km

The final result is:

3972 dm → 0.3972 km

We conclude that 3972 decimeters is equivalent to 0.3972 kilometers:

3972 decimeters = 0.3972 kilometers
