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 4218 decimeters into kilometers we have to multiply 4218 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

4218 dm → L_(km)

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

L_(km) = 4218 dm × 0.0001 km

L_(km) = 0.4218 km

The final result is:

4218 dm → 0.4218 km

We conclude that 4218 decimeters is equivalent to 0.4218 kilometers:

4218 decimeters = 0.4218 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.3707918444761 × 4218 decimeters.

Another way is saying that 4218 decimeters is equal to 1 ÷ 2.3707918444761 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 eighteen decimeters is approximately zero point four two two kilometers:

4218 dm ≅ 0.422 km

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