I just looked at one of my barbecue tanks and it says 15.0 lbs. Propane
weighs about 4 lb/gal so obviously my tank is short over a gallon. Some
places refill by the gallon but prefilled run short. Never got a reply on
this deception from state AG but rules may be different in different
states. Bet most consumers think they are getting 5 gal of propane in the
filled 5 gal tanks.

LPG tanks are filled to 80% of capacity.

And 80% of capacity on a "20 lb" tank is 20 lbs of propane - roughly
5 Yankee gallons.
