## 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 20.3 centimeters into decimeters we have to multiply 20.3 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

20.3 cm → L_{(dm)}

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

L_{(dm)} = 20.3 cm × 0.1 dm

L_{(dm)} = 2.03 dm

The final result is:

20.3 cm → 2.03 dm

We conclude that **20.3 centimeters is equivalent to 2.03 decimeters**:

20.3 centimeters = 2.03 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 decimeter is equal to 0.49261083743842 × 20.3 centimeters**.

Another way is saying that *20.3 centimeters is equal to 1 ÷ 0.49261083743842 decimeters*.

## Approximate result

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

20.3 cm ≅ 2.03 dm

An alternative is also that *one decimeter is approximately zero point four nine three times twenty point three centimeters*.
