## 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 18 centimeters into decimeters we have to multiply 18 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

18 cm → L_{(dm)}

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

L_{(dm)} = 18 cm × 0.1 dm

L_{(dm)} = 1.8 dm

The final result is:

18 cm → 1.8 dm

We conclude that **18 centimeters is equivalent to 1.8 decimeters**:

18 centimeters = 1.8 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 decimeter is equal to 0.55555555555556 × 18 centimeters**.

Another way is saying that *18 centimeters is equal to 1 ÷ 0.55555555555556 decimeters*.

## Approximate result

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

18 cm ≅ 1.8 dm

An alternative is also that *one decimeter is approximately zero point five five six times eighteen centimeters*.
