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 721 decimeters into kilometers we have to multiply 721 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

721 dm → L_(km)

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

L_(km) = 721 dm × 0.0001 km

L_(km) = 0.0721 km

The final result is:

721 dm → 0.0721 km

We conclude that 721 decimeters is equivalent to 0.0721 kilometers:

721 decimeters = 0.0721 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 13.869625520111 × 721 decimeters.

Another way is saying that 721 decimeters is equal to 1 ÷ 13.869625520111 kilometers.

Approximate result

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

721 dm ≅ 0.072 km

An alternative is also that one kilometer is approximately thirteen point eight seven times seven hundred twenty-one decimeters.
