That equation is wind equals the square root of 195 times weight over area of object in square feet. Brings you back to your algebra days, right?
Lets look at a maple leaf. Using the formula, it only takes a wind of 3 mph to move a maple leaf. A trash can with trash in it weighting 37 pounds could be moved by a 28 mph wind.
