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 820 centimeters into decimeters we have to multiply 820 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

820 cm → L_(dm)

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

L_(dm) = 820 cm × 0.1 dm

L_(dm) = 82 dm

The final result is:

820 cm → 82 dm

We conclude that 820 centimeters is equivalent to 82 decimeters:

820 centimeters = 82 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.01219512195122 × 820 centimeters.

Another way is saying that 820 centimeters is equal to 1 ÷ 0.01219512195122 decimeters.

Approximate result

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

820 cm ≅ 82 dm

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