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 493 decimeters into kilometers we have to multiply 493 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

493 dm → L_(km)

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

L_(km) = 493 dm × 0.0001 km

L_(km) = 0.0493 km

The final result is:

493 dm → 0.0493 km

We conclude that 493 decimeters is equivalent to 0.0493 kilometers:

493 decimeters = 0.0493 kilometers

Alternative conversion
