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 999 decimeters into kilometers we have to multiply 999 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

999 dm → L_(km)

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

L_(km) = 999 dm × 0.0001 km

L_(km) = 0.0999 km

The final result is:

999 dm → 0.0999 km

We conclude that 999 decimeters is equivalent to 0.0999 kilometers:

999 decimeters = 0.0999 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 10.01001001001 × 999 decimeters.

Another way is saying that 999 decimeters is equal to 1 ÷ 10.01001001001 kilometers.

Approximate result

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

999 dm ≅ 0.1 km

An alternative is also that one kilometer is approximately ten point zero one times nine hundred ninety-nine decimeters.
