Conversion formula
How to convert 20 decimeters to centimeters?
We know (by definition) that: 1 dm = 10 cm.
We can set up a proportion to solve for the number of centimeters.
1 dm / 20 dm = 10 cm / x cm
Now, we cross multiply to solve for our unknown x:
x cm = (20 dm / 1 dm) * 10 cm → x cm = 200 cm
Conclusion:
20 dm = 200 cm
