Conversion formula

The conversion factor from millimeters to decimeters is 0.01, which means that 1 millimeter is equal to 0.01 decimeters:

1 mm = 0.01 dm

To convert 720 millimeters into decimeters we have to multiply 720 by the conversion factor in order to get the length amount from millimeters to decimeters. We can also form a simple proportion to calculate the result:

1 mm → 0.01 dm

720 mm → L_(dm)

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

L_(dm) = 720 mm × 0.01 dm

L_(dm) = 7.2 dm

The final result is:

720 mm → 7.2 dm

We conclude that 720 millimeters is equivalent to 7.2 decimeters:

720 millimeters = 7.2 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.13888888888889 × 720 millimeters.

Another way is saying that 720 millimeters is equal to 1 ÷ 0.13888888888889 decimeters.

Approximate result

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

720 mm ≅ 7.2 dm

An alternative is also that one decimeter is approximately zero point one three nine times seven hundred twenty millimeters.
