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 7220 decimeters into kilometers we have to multiply 7220 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

7220 dm → L_(km)

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

L_(km) = 7220 dm × 0.0001 km

L_(km) = 0.722 km

The final result is:

7220 dm → 0.722 km

We conclude that 7220 decimeters is equivalent to 0.722 kilometers:

7220 decimeters = 0.722 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 1.3850415512465 × 7220 decimeters.

Another way is saying that 7220 decimeters is equal to 1 ÷ 1.3850415512465 kilometers.

Approximate result

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

7220 dm ≅ 0.722 km

An alternative is also that one kilometer is approximately one point three eight five times seven thousand two hundred twenty decimeters.
