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 345.7 decimeters into kilometers we have to multiply 345.7 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

345.7 dm → L_(km)

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

L_(km) = 345.7 dm × 0.0001 km

L_(km) = 0.03457 km

The final result is:

345.7 dm → 0.03457 km

We conclude that 345.7 decimeters is equivalent to 0.03457 kilometers:

345.7 decimeters = 0.03457 kilometers

Alternative conversion
