## 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 138 centimeters into decimeters we have to multiply 138 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

138 cm → L(dm)

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

L(dm) = 138 cm × 0.1 dm

L(dm) = 13.8 dm

The final result is:

138 cm → 13.8 dm

We conclude that 138 centimeters is equivalent to 13.8 decimeters:

138 centimeters = 13.8 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.072463768115942 × 138 centimeters.

Another way is saying that 138 centimeters is equal to 1 ÷ 0.072463768115942 decimeters.

## Approximate result

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

138 cm ≅ 13.8 dm

An alternative is also that one decimeter is approximately zero point zero seven two times one hundred thirty-eight centimeters.
