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 998 decimeters into kilometers we have to multiply 998 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

998 dm → L_(km)

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

L_(km) = 998 dm × 0.0001 km

L_(km) = 0.0998 km

The final result is:

998 dm → 0.0998 km

We conclude that 998 decimeters is equivalent to 0.0998 kilometers:

998 decimeters = 0.0998 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 10.02004008016 × 998 decimeters.

Another way is saying that 998 decimeters is equal to 1 ÷ 10.02004008016 kilometers.

Approximate result

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

998 dm ≅ 0.1 km

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