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 0.9 decimeters into kilometers we have to multiply 0.9 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

0.9 dm → L_(km)

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

L_(km) = 0.9 dm × 0.0001 km

L_(km) = 9.0E-5 km

The final result is:

0.9 dm → 9.0E-5 km

We conclude that 0.9 decimeters is equivalent to 9.0E-5 kilometers:

0.9 decimeters = 9.0E-5 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 11111.111111111 × 0.9 decimeters.

Another way is saying that 0.9 decimeters is equal to 1 ÷ 11111.111111111 kilometers.

Approximate result

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

0.9 dm ≅ 0 km

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