## 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 3 centimeters into decimeters we have to multiply 3 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

3 cm → L(dm)

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

L(dm) = 3 cm × 0.1 dm

L(dm) = 0.3 dm

The final result is:

3 cm → 0.3 dm

We conclude that 3 centimeters is equivalent to 0.3 decimeters:

3 centimeters = 0.3 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 3.3333333333333 × 3 centimeters.

Another way is saying that 3 centimeters is equal to 1 ÷ 3.3333333333333 decimeters.

## Approximate result

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

3 cm ≅ 0.3 dm

An alternative is also that one decimeter is approximately three point three three three times three centimeters.
