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 100 centimeters into decimeters we have to multiply 100 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

100 cm → L_(dm)

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

L_(dm) = 100 cm × 0.1 dm

L_(dm) = 10 dm

The final result is:

100 cm → 10 dm

We conclude that 100 centimeters is equivalent to 10 decimeters:

100 centimeters = 10 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.1 × 100 centimeters.

Another way is saying that 100 centimeters is equal to 1 ÷ 0.1 decimeters.

Approximate result

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

100 cm ≅ 10 dm

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