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 422.1 decimeters into kilometers we have to multiply 422.1 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

422.1 dm → L_(km)

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

L_(km) = 422.1 dm × 0.0001 km

L_(km) = 0.04221 km

The final result is:

422.1 dm → 0.04221 km

We conclude that 422.1 decimeters is equivalent to 0.04221 kilometers:

422.1 decimeters = 0.04221 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 23.691068467188 × 422.1 decimeters.

Another way is saying that 422.1 decimeters is equal to 1 ÷ 23.691068467188 kilometers.

Approximate result

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

422.1 dm ≅ 0.042 km

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