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 4545 decimeters into kilometers we have to multiply 4545 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

4545 dm → L_(km)

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

L_(km) = 4545 dm × 0.0001 km

L_(km) = 0.4545 km

The final result is:

4545 dm → 0.4545 km

We conclude that 4545 decimeters is equivalent to 0.4545 kilometers:

4545 decimeters = 0.4545 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.2002200220022 × 4545 decimeters.

Another way is saying that 4545 decimeters is equal to 1 ÷ 2.2002200220022 kilometers.

Approximate result

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

4545 dm ≅ 0.455 km

An alternative is also that one kilometer is approximately two point two times four thousand five hundred forty-five decimeters.
