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 123 decimeters into kilometers we have to multiply 123 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

123 dm → L_(km)

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

L_(km) = 123 dm × 0.0001 km

L_(km) = 0.0123 km

The final result is:

123 dm → 0.0123 km

We conclude that 123 decimeters is equivalent to 0.0123 kilometers:

123 decimeters = 0.0123 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 81.30081300813 × 123 decimeters.

Another way is saying that 123 decimeters is equal to 1 ÷ 81.30081300813 kilometers.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that one hundred twenty-three decimeters is approximately zero point zero one two kilometers:

123 dm ≅ 0.012 km

An alternative is also that one kilometer is approximately eighty-one point three zero one times one hundred twenty-three decimeters.
