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 12.3 decimeters into centimeters we have to multiply 12.3 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

12.3 dm → L_(cm)

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

L_(cm) = 12.3 dm × 10 cm

L_(cm) = 123 cm

The final result is:

12.3 dm → 123 cm

We conclude that 12.3 decimeters is equivalent to 123 centimeters:

12.3 decimeters = 123 centimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 centimeter is equal to 0.008130081300813 × 12.3 decimeters.

Another way is saying that 12.3 decimeters is equal to 1 ÷ 0.008130081300813 centimeters.

Approximate result

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

12.3 dm ≅ 123 cm

An alternative is also that one centimeter is approximately zero point zero zero eight times twelve point three decimeters.
