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 6400 decimeters into kilometers we have to multiply 6400 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

6400 dm → L_(km)

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

L_(km) = 6400 dm × 0.0001 km

L_(km) = 0.64 km

The final result is:

6400 dm → 0.64 km

We conclude that 6400 decimeters is equivalent to 0.64 kilometers:

6400 decimeters = 0.64 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 1.5625 × 6400 decimeters.

Another way is saying that 6400 decimeters is equal to 1 ÷ 1.5625 kilometers.

Approximate result

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

6400 dm ≅ 0.64 km

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