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 842.4 decimeters into kilometers we have to multiply 842.4 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

842.4 dm → L_(km)

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

L_(km) = 842.4 dm × 0.0001 km

L_(km) = 0.08424 km

The final result is:

842.4 dm → 0.08424 km

We conclude that 842.4 decimeters is equivalent to 0.08424 kilometers:

842.4 decimeters = 0.08424 kilometers

Alternative conversion
