## 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 20.1 centimeters into decimeters we have to multiply 20.1 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

20.1 cm → L_{(dm)}

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

L_{(dm)} = 20.1 cm × 0.1 dm

L_{(dm)} = 2.01 dm

The final result is:

20.1 cm → 2.01 dm

We conclude that **20.1 centimeters is equivalent to 2.01 decimeters**:

20.1 centimeters = 2.01 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 decimeter is equal to 0.49751243781095 × 20.1 centimeters**.

Another way is saying that *20.1 centimeters is equal to 1 ÷ 0.49751243781095 decimeters*.

## Approximate result

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

20.1 cm ≅ 2.01 dm

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