## 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 78 centimeters into decimeters we have to multiply 78 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

78 cm → L_{(dm)}

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

L_{(dm)} = 78 cm × 0.1 dm

L_{(dm)} = 7.8 dm

The final result is:

78 cm → 7.8 dm

We conclude that **78 centimeters is equivalent to 7.8 decimeters**:

78 centimeters = 7.8 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 decimeter is equal to 0.12820512820513 × 78 centimeters**.

Another way is saying that *78 centimeters is equal to 1 ÷ 0.12820512820513 decimeters*.

## Approximate result

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

78 cm ≅ 7.8 dm

An alternative is also that *one decimeter is approximately zero point one two eight times seventy-eight centimeters*.
