Conversion formula

The conversion factor from decimeters to centimeters is 10, which means that 1 decimeter is equal to 10 centimeters:

1 dm = 10 cm

To convert 120 decimeters into centimeters we have to multiply 120 by the conversion factor in order to get the length amount from decimeters to centimeters. We can also form a simple proportion to calculate the result:

1 dm → 10 cm

120 dm → L_(cm)

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

L_(cm) = 120 dm × 10 cm

L_(cm) = 1200 cm

The final result is:

120 dm → 1200 cm

We conclude that 120 decimeters is equivalent to 1200 centimeters:

120 decimeters = 1200 centimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 centimeter is equal to 0.00083333333333333 × 120 decimeters.

Another way is saying that 120 decimeters is equal to 1 ÷ 0.00083333333333333 centimeters.

Approximate result

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

120 dm ≅ 1200 cm

An alternative is also that one centimeter is approximately zero point zero zero one times one hundred twenty decimeters.
