## 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 66 centimeters into decimeters we have to multiply 66 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

66 cm → L(dm)

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

L(dm) = 66 cm × 0.1 dm

L(dm) = 6.6 dm

The final result is:

66 cm → 6.6 dm

We conclude that 66 centimeters is equivalent to 6.6 decimeters:

66 centimeters = 6.6 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.15151515151515 × 66 centimeters.

Another way is saying that 66 centimeters is equal to 1 ÷ 0.15151515151515 decimeters.

## Approximate result

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

66 cm ≅ 6.6 dm

An alternative is also that one decimeter is approximately zero point one five two times sixty-six centimeters.
