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 9800 decimeters into kilometers we have to multiply 9800 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

9800 dm → L_(km)

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

L_(km) = 9800 dm × 0.0001 km

L_(km) = 0.98 km

The final result is:

9800 dm → 0.98 km

We conclude that 9800 decimeters is equivalent to 0.98 kilometers:

9800 decimeters = 0.98 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 1.0204081632653 × 9800 decimeters.

Another way is saying that 9800 decimeters is equal to 1 ÷ 1.0204081632653 kilometers.

Approximate result

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

9800 dm ≅ 0.98 km

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