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 790 millimeters into decimeters we have to multiply 790 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

790 mm → L_(dm)

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

L_(dm) = 790 mm × 0.01 dm

L_(dm) = 7.9 dm

The final result is:

790 mm → 7.9 dm

We conclude that 790 millimeters is equivalent to 7.9 decimeters:

790 millimeters = 7.9 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.12658227848101 × 790 millimeters.

Another way is saying that 790 millimeters is equal to 1 ÷ 0.12658227848101 decimeters.

Approximate result

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

790 mm ≅ 7.9 dm

An alternative is also that one decimeter is approximately zero point one two seven times seven hundred ninety millimeters.
