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 9980 decimeters into kilometers we have to multiply 9980 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

9980 dm → L_(km)

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

L_(km) = 9980 dm × 0.0001 km

L_(km) = 0.998 km

The final result is:

9980 dm → 0.998 km

We conclude that 9980 decimeters is equivalent to 0.998 kilometers:

9980 decimeters = 0.998 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 1.002004008016 × 9980 decimeters.

Another way is saying that 9980 decimeters is equal to 1 ÷ 1.002004008016 kilometers.

Approximate result

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

9980 dm ≅ 0.998 km

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