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 456.4 decimeters into kilometers we have to multiply 456.4 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

456.4 dm → L_(km)

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

L_(km) = 456.4 dm × 0.0001 km

L_(km) = 0.04564 km

The final result is:

456.4 dm → 0.04564 km

We conclude that 456.4 decimeters is equivalent to 0.04564 kilometers:
