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 1000 centimeters into decimeters we have to multiply 1000 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

1000 cm → L_(dm)

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

L_(dm) = 1000 cm × 0.1 dm

L_(dm) = 100 dm

The final result is:

1000 cm → 100 dm

We conclude that 1000 centimeters is equivalent to 100 decimeters:

1000 centimeters = 100 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.01 × 1000 centimeters.

Another way is saying that 1000 centimeters is equal to 1 ÷ 0.01 decimeters.

Approximate result

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

1000 cm ≅ 100 dm

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