## 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 13.8 centimeters into decimeters we have to multiply 13.8 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

13.8 cm → L(dm)

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

L(dm) = 13.8 cm × 0.1 dm

L(dm) = 1.38 dm

The final result is:

13.8 cm → 1.38 dm

We conclude that 13.8 centimeters is equivalent to 1.38 decimeters:

13.8 centimeters = 1.38 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.72463768115942 × 13.8 centimeters.

Another way is saying that 13.8 centimeters is equal to 1 ÷ 0.72463768115942 decimeters.

## Approximate result

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

13.8 cm ≅ 1.38 dm

An alternative is also that one decimeter is approximately zero point seven two five times thirteen point eight centimeters.
