They can be interchangeable with gallons or pounds but you have to be good at math. A gallon of propane goes about 4.7 pounds as I recall. You can Google if you have lots of time...
The tanks used for gas grills are usually called 20 pound tanks. On the band that runs around the bottom of the tank, there is a number stamped. That is the weight of the tank when empty. Usually something like 19.4 or 19.7. So when the tank is put on the scale, they can tell how empty the tank is. So if you put a 19.7 pound tank on the scale, and fill it, it should weigh 39.7 pounds when filled. A shop I worked at used to fill tanks and the lady that filled them used to open the tank to be sure it was empty. I got that stopped in a hurry. Then she didn't watch the scale, she ran the pump until it started groaning under a heavy load. That was when she decided it was full. The owner decided she shouldn't fill any more tanks... ----- Original Message ----- From: Joe Plummer To: blindhandyman@yahoogroups.com Sent: Saturday, January 16, 2010 7:14 AM Subject: RE: [BlindHandyMan] Propane Tank Sizes Unless you are in another country beside the USA bulk propane tanks are measured in gallons not pounds.
