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 90 decimeters into kilometers we have to multiply 90 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

90 dm → L_(km)

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

L_(km) = 90 dm × 0.0001 km

L_(km) = 0.009 km

The final result is:

90 dm → 0.009 km

We conclude that 90 decimeters is equivalent to 0.009 kilometers:

90 decimeters = 0.009 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 111.11111111111 × 90 decimeters.

Another way is saying that 90 decimeters is equal to 1 ÷ 111.11111111111 kilometers.

Approximate result

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

90 dm ≅ 0.009 km

An alternative is also that one kilometer is approximately one hundred eleven point one one one times ninety decimeters.
