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 4242 decimeters into kilometers we have to multiply 4242 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

4242 dm → L_(km)

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

L_(km) = 4242 dm × 0.0001 km

L_(km) = 0.4242 km

The final result is:

4242 dm → 0.4242 km

We conclude that 4242 decimeters is equivalent to 0.4242 kilometers:

4242 decimeters = 0.4242 kilometers
