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 668 decimeters into kilometers we have to multiply 668 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

668 dm → L_(km)

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

L_(km) = 668 dm × 0.0001 km

L_(km) = 0.0668 km

The final result is:

668 dm → 0.0668 km

We conclude that 668 decimeters is equivalent to 0.0668 kilometers:

668 decimeters = 0.0668 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 14.97005988024 × 668 decimeters.

Another way is saying that 668 decimeters is equal to 1 ÷ 14.97005988024 kilometers.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that six hundred sixty-eight decimeters is approximately zero point zero six seven kilometers:

668 dm ≅ 0.067 km

An alternative is also that one kilometer is approximately fourteen point nine seven times six hundred sixty-eight decimeters.
