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 6840 decimeters into kilometers we have to multiply 6840 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

6840 dm → L_(km)

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

L_(km) = 6840 dm × 0.0001 km

L_(km) = 0.684 km

The final result is:

6840 dm → 0.684 km

We conclude that 6840 decimeters is equivalent to 0.684 kilometers:

6840 decimeters = 0.684 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 1.4619883040936 × 6840 decimeters.

Another way is saying that 6840 decimeters is equal to 1 ÷ 1.4619883040936 kilometers.

Approximate result

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

6840 dm ≅ 0.684 km

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