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 900 decimeters into kilometers we have to multiply 900 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

900 dm → L_(km)

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

L_(km) = 900 dm × 0.0001 km

L_(km) = 0.09 km

The final result is:

900 dm → 0.09 km

We conclude that 900 decimeters is equivalent to 0.09 kilometers:

900 decimeters = 0.09 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 11.111111111111 × 900 decimeters.

Another way is saying that 900 decimeters is equal to 1 ÷ 11.111111111111 kilometers.

Approximate result

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

900 dm ≅ 0.09 km

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