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 4042 decimeters into kilometers we have to multiply 4042 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

4042 dm → L_(km)

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

L_(km) = 4042 dm × 0.0001 km

L_(km) = 0.4042 km

The final result is:

4042 dm → 0.4042 km

We conclude that 4042 decimeters is equivalent to 0.4042 kilometers:

4042 decimeters = 0.4042 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.4740227610094 × 4042 decimeters.

Another way is saying that 4042 decimeters is equal to 1 ÷ 2.4740227610094 kilometers.

Approximate result

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

4042 dm ≅ 0.404 km

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