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 498 decimeters into kilometers we have to multiply 498 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

498 dm → L_(km)

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

L_(km) = 498 dm × 0.0001 km

L_(km) = 0.0498 km

The final result is:

498 dm → 0.0498 km

We conclude that 498 decimeters is equivalent to 0.0498 kilometers:

498 decimeters = 0.0498 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 20.080321285141 × 498 decimeters.

Another way is saying that 498 decimeters is equal to 1 ÷ 20.080321285141 kilometers.

Approximate result

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

498 dm ≅ 0.05 km

An alternative is also that one kilometer is approximately twenty point zero eight times four hundred ninety-eight decimeters.
