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 680 decimeters into kilometers we have to multiply 680 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

680 dm → L_(km)

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

L_(km) = 680 dm × 0.0001 km

L_(km) = 0.068 km

The final result is:

680 dm → 0.068 km

We conclude that 680 decimeters is equivalent to 0.068 kilometers:

680 decimeters = 0.068 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 14.705882352941 × 680 decimeters.

Another way is saying that 680 decimeters is equal to 1 ÷ 14.705882352941 kilometers.

Approximate result

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

680 dm ≅ 0.068 km

An alternative is also that one kilometer is approximately fourteen point seven zero six times six hundred eighty decimeters.
