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 8400 decimeters into kilometers we have to multiply 8400 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

8400 dm → L_(km)

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

L_(km) = 8400 dm × 0.0001 km

L_(km) = 0.84 km

The final result is:

8400 dm → 0.84 km

We conclude that 8400 decimeters is equivalent to 0.84 kilometers:

8400 decimeters = 0.84 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 1.1904761904762 × 8400 decimeters.

Another way is saying that 8400 decimeters is equal to 1 ÷ 1.1904761904762 kilometers.

Approximate result

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

8400 dm ≅ 0.84 km

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