## 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 39 centimeters into decimeters we have to multiply 39 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

39 cm → L(dm)

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

L(dm) = 39 cm × 0.1 dm

L(dm) = 3.9 dm

The final result is:

39 cm → 3.9 dm

We conclude that 39 centimeters is equivalent to 3.9 decimeters:

39 centimeters = 3.9 decimeters ## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.25641025641026 × 39 centimeters.

Another way is saying that 39 centimeters is equal to 1 ÷ 0.25641025641026 decimeters.

## Approximate result

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

39 cm ≅ 3.9 dm

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