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 4980 decimeters into kilometers we have to multiply 4980 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

4980 dm → L_(km)

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

L_(km) = 4980 dm × 0.0001 km

L_(km) = 0.498 km

The final result is:

4980 dm → 0.498 km

We conclude that 4980 decimeters is equivalent to 0.498 kilometers:

4980 decimeters = 0.498 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.0080321285141 × 4980 decimeters.

Another way is saying that 4980 decimeters is equal to 1 ÷ 2.0080321285141 kilometers.

Approximate result

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

4980 dm ≅ 0.498 km

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