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 138 decimeters into kilometers we have to multiply 138 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

138 dm → L_(km)

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

L_(km) = 138 dm × 0.0001 km

L_(km) = 0.0138 km

The final result is:

138 dm → 0.0138 km

We conclude that 138 decimeters is equivalent to 0.0138 kilometers:

138 decimeters = 0.0138 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 72.463768115942 × 138 decimeters.

Another way is saying that 138 decimeters is equal to 1 ÷ 72.463768115942 kilometers.

Approximate result

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

138 dm ≅ 0.014 km

An alternative is also that one kilometer is approximately seventy-two point four six four times one hundred thirty-eight decimeters.
