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 4002 decimeters into kilometers we have to multiply 4002 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

4002 dm → L_(km)

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

L_(km) = 4002 dm × 0.0001 km

L_(km) = 0.4002 km

The final result is:

4002 dm → 0.4002 km

We conclude that 4002 decimeters is equivalent to 0.4002 kilometers:

4002 decimeters = 0.4002 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.4987506246877 × 4002 decimeters.

Another way is saying that 4002 decimeters is equal to 1 ÷ 2.4987506246877 kilometers.

Approximate result

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

4002 dm ≅ 0.4 km

An alternative is also that one kilometer is approximately two point four nine nine times four thousand two decimeters.
