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 389 decimeters into kilometers we have to multiply 389 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

389 dm → L_(km)

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

L_(km) = 389 dm × 0.0001 km

L_(km) = 0.0389 km

The final result is:

389 dm → 0.0389 km

We conclude that 389 decimeters is equivalent to 0.0389 kilometers:

389 decimeters = 0.0389 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 25.706940874036 × 389 decimeters.

Another way is saying that 389 decimeters is equal to 1 ÷ 25.706940874036 kilometers.

Approximate result

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

389 dm ≅ 0.039 km

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