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 1020 centimeters into decimeters we have to multiply 1020 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

1020 cm → L_(dm)

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

L_(dm) = 1020 cm × 0.1 dm

L_(dm) = 102 dm

The final result is:

1020 cm → 102 dm

We conclude that 1020 centimeters is equivalent to 102 decimeters:

1020 centimeters = 102 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.0098039215686275 × 1020 centimeters.

Another way is saying that 1020 centimeters is equal to 1 ÷ 0.0098039215686275 decimeters.

Approximate result

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

1020 cm ≅ 102 dm

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