Actually, the easiest and most accurate way is to weigh the tank. Bathroom
scales will do nicely.
The typical 20# tank weighs about 18# empty, and of course, 38# full.
Some tanks will differ on the empty weight, so to be sure, just look for the
Tare Weight (TW) stamped into the valve guard (or carrying handle).
