## 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 80 centimeters into decimeters we have to multiply 80 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

80 cm → L(dm)

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

L(dm) = 80 cm × 0.1 dm

L(dm) = 8 dm

The final result is:

80 cm → 8 dm

We conclude that 80 centimeters is equivalent to 8 decimeters:

80 centimeters = 8 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.125 × 80 centimeters.

Another way is saying that 80 centimeters is equal to 1 ÷ 0.125 decimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that eighty centimeters is approximately eight decimeters:

80 cm ≅ 8 dm

An alternative is also that one decimeter is approximately zero point one two five times eighty centimeters.
