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 4997 decimeters into kilometers we have to multiply 4997 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

4997 dm → L_(km)

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

L_(km) = 4997 dm × 0.0001 km

L_(km) = 0.4997 km

The final result is:

4997 dm → 0.4997 km

We conclude that 4997 decimeters is equivalent to 0.4997 kilometers:

4997 decimeters = 0.4997 kilometers
