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 3155 decimeters into kilometers we have to multiply 3155 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

3155 dm → L_(km)

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

L_(km) = 3155 dm × 0.0001 km

L_(km) = 0.3155 km

The final result is:

3155 dm → 0.3155 km

We conclude that 3155 decimeters is equivalent to 0.3155 kilometers:

3155 decimeters = 0.3155 kilometers
