A "30 pound" propane tank holds 30 pounds of propane, more or less.
Somewhere on the tank will be stamped a number, for example, TW 23.
TW stands for "Tare Weight", that is, the weight of the empty tank. So if you have a scales to weight the tanks, the propane content is the weight less the Tare Weight.
