"People who cry foul because a 20lb cylinder does not actually have 20lbs of propane in it really need to educate themselves."
The capacity of a 20lb cylinder is greater than 4.7 gallon. A typical 20lb cylinder has water capacity of 47.8lbs (stamped into the collar). The cylinder empty is 17.8lbs. Adding 20lbs of propane to the empty weight makes it 37.8lbs. or about 78% of the total capacity
