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 478 decimeters into kilometers we have to multiply 478 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

478 dm → L_(km)

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

L_(km) = 478 dm × 0.0001 km

L_(km) = 0.0478 km

The final result is:

478 dm → 0.0478 km

We conclude that 478 decimeters is equivalent to 0.0478 kilometers:

478 decimeters = 0.0478 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 20.92050209205 × 478 decimeters.

Another way is saying that 478 decimeters is equal to 1 ÷ 20.92050209205 kilometers.

Approximate result

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

478 dm ≅ 0.048 km

An alternative is also that one kilometer is approximately twenty point nine two one times four hundred seventy-eight decimeters.
