The barbeque sized ones; about how much are they full and empty?

The last one I had that was empty weighed exactly 17 lbs. 14 oz. on my
refrigerant scale which is fairly accurate. The new one weighed 37 lbs.
4.5 oz. full, and the tare weight is listed as 17 lbs. Which gives a net
of 20 lbs and 4.5 oz. of propane which is interesting because it's sold as
17 lbs. net weight, as many exchange cylinders are now (Blue Rhino,
etc.).

It's deceiving. IF the geek fills your tank by the book, they don't fill it
to 100%, but rather 80 or 85 to allow for thermal expansion if the tank gets
hot. This coupled with filling a partially full tank, and trying to do the
math on the fly with those meters that all seem to be ancient can give some
questionable answers.

They usually ask two questions ...... you want it ........ or not?
