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 18 decimeters into centimeters we have to multiply 18 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

18 dm → L_(cm)

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

L_(cm) = 18 dm × 10 cm

L_(cm) = 180 cm

The final result is:

18 dm → 180 cm

We conclude that 18 decimeters is equivalent to 180 centimeters:

18 decimeters = 180 centimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 centimeter is equal to 0.0055555555555556 × 18 decimeters.

Another way is saying that 18 decimeters is equal to 1 ÷ 0.0055555555555556 centimeters.

Approximate result

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

18 dm ≅ 180 cm

An alternative is also that one centimeter is approximately zero point zero zero six times eighteen decimeters.
