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 1009 decimeters into kilometers we have to multiply 1009 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

1009 dm → L_(km)

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

L_(km) = 1009 dm × 0.0001 km

L_(km) = 0.1009 km

The final result is:

1009 dm → 0.1009 km

We conclude that 1009 decimeters is equivalent to 0.1009 kilometers:

1009 decimeters = 0.1009 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 9.9108027750248 × 1009 decimeters.

Another way is saying that 1009 decimeters is equal to 1 ÷ 9.9108027750248 kilometers.

Approximate result

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

1009 dm ≅ 0.101 km

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