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 455 decimeters into kilometers we have to multiply 455 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

455 dm → L_(km)

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

L_(km) = 455 dm × 0.0001 km

L_(km) = 0.0455 km

The final result is:

455 dm → 0.0455 km

We conclude that 455 decimeters is equivalent to 0.0455 kilometers:

455 decimeters = 0.0455 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 21.978021978022 × 455 decimeters.

Another way is saying that 455 decimeters is equal to 1 ÷ 21.978021978022 kilometers.

Approximate result

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

455 dm ≅ 0.046 km

An alternative is also that one kilometer is approximately twenty-one point nine seven eight times four hundred fifty-five decimeters.
