## 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 30.8 centimeters into decimeters we have to multiply 30.8 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

30.8 cm → L_{(dm)}

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

L_{(dm)} = 30.8 cm × 0.1 dm

L_{(dm)} = 3.08 dm

The final result is:

30.8 cm → 3.08 dm

We conclude that **30.8 centimeters is equivalent to 3.08 decimeters**:

30.8 centimeters = 3.08 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 decimeter is equal to 0.32467532467532 × 30.8 centimeters**.

Another way is saying that *30.8 centimeters is equal to 1 ÷ 0.32467532467532 decimeters*.

## Approximate result

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

30.8 cm ≅ 3.08 dm

An alternative is also that *one decimeter is approximately zero point three two five times thirty point eight centimeters*.
