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 425.4 decimeters into kilometers we have to multiply 425.4 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

425.4 dm → L_(km)

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

L_(km) = 425.4 dm × 0.0001 km

L_(km) = 0.04254 km

The final result is:

425.4 dm → 0.04254 km

We conclude that 425.4 decimeters is equivalent to 0.04254 kilometers:

425.4 decimeters = 0.04254 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 23.50728725905 × 425.4 decimeters.

Another way is saying that 425.4 decimeters is equal to 1 ÷ 23.50728725905 kilometers.

Approximate result

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

425.4 dm ≅ 0.043 km

An alternative is also that one kilometer is approximately twenty-three point five zero seven times four hundred twenty-five point four decimeters.
