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 423 decimeters into kilometers we have to multiply 423 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

423 dm → L_(km)

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

L_(km) = 423 dm × 0.0001 km

L_(km) = 0.0423 km

The final result is:

423 dm → 0.0423 km

We conclude that 423 decimeters is equivalent to 0.0423 kilometers:

423 decimeters = 0.0423 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 23.640661938534 × 423 decimeters.

Another way is saying that 423 decimeters is equal to 1 ÷ 23.640661938534 kilometers.

Approximate result

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

423 dm ≅ 0.042 km

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