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 9 centimeters into decimeters we have to multiply 9 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

9 cm → L_(dm)

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

L_(dm) = 9 cm × 0.1 dm

L_(dm) = 0.9 dm

The final result is:

9 cm → 0.9 dm

We conclude that 9 centimeters is equivalent to 0.9 decimeters:

9 centimeters = 0.9 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 1.1111111111111 × 9 centimeters.

Another way is saying that 9 centimeters is equal to 1 ÷ 1.1111111111111 decimeters.

Approximate result

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

9 cm ≅ 0.9 dm

An alternative is also that one decimeter is approximately one point one one one times nine centimeters.
