## 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.
