Another propane question
I went to fill my 20# bottle just now and the guy set the scale at 39 lbs. I told him I didn't think that would fill it but he said it would. I needed propane but I think he was wrong. Opinions?

20# IS 80 percent of cylinders full capacity (or 30#, 40# etc)
Why do people insist on this? It is not true.
20# is the 100 percent capacity of a 20# cylinder. A 20# cylinder only holds 5 gallons of liquid, filled to the neck. 5 gallons of liquid propane weighs 20#. How can it otherwise? It is the same height and diameter as the ubiquitous "5 gallon bucket," which is also filled to the rim when it contains 5 gallons of liquid.
Like anything else, the manufacturers use whatever they can to make their product sound bigger, better, more capable than it really is. Vacuum cleaners with "13 Amp" motors, for example. Yeah, 13 Amps is the current when the motor is STALLED, i.e. not "sucking." So, really, a lie. Cargo capacity of a car/truck/van in cubic feet is another little white lie, because it includes every useless nook and cranny in the vehicle. 100 Watts per channel on your stereo. If you push 100 Watts through each channel, the sound is so distorted you can't understand what Rush Limbaugh is saying!
If a 20# propane tank could really hold 25# of propane filled to the brim, you can rest assured manufactures would have called it a 25# tank from the get-go.
