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 1645 decimeters into kilometers we have to multiply 1645 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

1645 dm → L_(km)

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

L_(km) = 1645 dm × 0.0001 km

L_(km) = 0.1645 km

The final result is:

1645 dm → 0.1645 km

We conclude that 1645 decimeters is equivalent to 0.1645 kilometers:

1645 decimeters = 0.1645 kilometers

Alternative conversion
