20 dm to cm - How long is 20 decimeters in centimeters? [CONVERT] ✔
20 decimeters is equivalent to 200 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 cmNow, we cross multiply to solve for our unknown x:
x cm = 20 dm 1 dm * 10 cm → x cm = 200 cmConclusion: 20 dm = 200 cm
The inverse of the conversion factor is that 1 centimeter is equal to 0.005 times 20 decimeters.
It can also be expressed as: 20 decimeters is equal to 1 0.005 centimeters.
