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 4202 decimeters into kilometers we have to multiply 4202 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

4202 dm → L_(km)

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

L_(km) = 4202 dm × 0.0001 km

L_(km) = 0.4202 km

The final result is:

4202 dm → 0.4202 km

We conclude that 4202 decimeters is equivalent to 0.4202 kilometers:

4202 decimeters = 0.4202 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.3798191337458 × 4202 decimeters.

Another way is saying that 4202 decimeters is equal to 1 ÷ 2.3798191337458 kilometers.

Approximate result

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

4202 dm ≅ 0.42 km

An alternative is also that one kilometer is approximately two point three eight times four thousand two hundred two decimeters.
