## Conversion formula

The conversion factor from centimeters to decimeters is 0.1, which means that 1 centimeter is equal to 0.1 decimeters:

1 cm = 0.1 dm

To convert 7.9 centimeters into decimeters we have to multiply 7.9 by the conversion factor in order to get the length amount from centimeters to decimeters. We can also form a simple proportion to calculate the result:

1 cm → 0.1 dm

7.9 cm → L(dm)

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

L(dm) = 7.9 cm × 0.1 dm

L(dm) = 0.79 dm

The final result is:

7.9 cm → 0.79 dm

We conclude that 7.9 centimeters is equivalent to 0.79 decimeters:

7.9 centimeters = 0.79 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 1.2658227848101 × 7.9 centimeters.

Another way is saying that 7.9 centimeters is equal to 1 ÷ 1.2658227848101 decimeters.

## Approximate result

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

7.9 cm ≅ 0.79 dm

An alternative is also that one decimeter is approximately one point two six six times seven point nine centimeters.
