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 1200 centimeters into decimeters we have to multiply 1200 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

1200 cm → L_(dm)

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

L_(dm) = 1200 cm × 0.1 dm

L_(dm) = 120 dm

The final result is:

1200 cm → 120 dm

We conclude that 1200 centimeters is equivalent to 120 decimeters:

1200 centimeters = 120 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.0083333333333333 × 1200 centimeters.

Another way is saying that 1200 centimeters is equal to 1 ÷ 0.0083333333333333 decimeters.

Approximate result

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

1200 cm ≅ 120 dm

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