Conversion formula
How to convert 123 centimeters to decimeters?

We know (by definition) that: 1 cm = 0.1 dm.

We can set up a proportion to solve for the number of decimeters.

1 cm / 123 cm = 0.1 dm / x dm

Now, we cross multiply to solve for our unknown x:

x dm = (123 cm / 1 cm) * 0.1 dm → x dm = 12.3 dm

Conclusion:

123 cm = 12.3 dm
