This chart will let you do the math to compare propane sold by the lb to the gallon:

Propane and propane generators

Propane weighs 4.2 pounds per gallon
Cylinders are rated by their weight capacity of propane

There is also a lot of other interesting info on power and consumption rates.

Pretty interesting site. One small problem: Cylinders are rated by their weight capacity for water, not propane. If you look at the collar of your cylinder, you'll see a number after the acronym WC, which stands for water capacity; there's no indication for capacity in pounds of propane. (If you multiply WC by .42, you'll get the weight capacity for propane.)

What I didn't see in the site was anything specific about how dealers charge for propane, gallon vs. pound. If there's any difference at all, I suspect it would be a fairly small one. However, the gallon counters commonly used to sell propane aren't very accurate because these simple counters do not compensate for temperature. (That's the reason why the NFPA does not condone filling propane cylinders -- the safety concern -- by means of a simple gallon counter.)

Lynn,
Last winter when I stopped in MN. I was charged by the pound. The local Propane dealer charges by the gallon. I have seen both. About $2.20/gal cost to fill around $20 and around $1.00/lb for my cylinder it comes to about $30.

Any way back on topic.....

The gage on the regulator stays green till it just about goes empty and then turns red as it goes empty.....

Has anyone tried on of those gages that they sell at wally world, or other camping stores... Do any of those gages work, or is water down the side the most reliable test... And what if your tanks are in a cover, makes it hard to do...

Any thoughts...???????

Jason, My regulator has the same gauge you described. It turns green when there is propane, then suddenly turns red when you are out. I gives no notice or capacity at all. I have been caught with my tank low and not know it. Running out while cooking breakfast for your family and your neighbors is rather embarrassing. I kind of wish I had bought the Worthington's with the gauges on them that Vintage Trailer Supply sells.
I prefer to have my tanks filled at my local rv center. It costs more (I do not know what it costs for all Airstream expenses are ignored as to not put a dollar figure on a priceless hobby) but when Freddie fills the tanks he opens the bleeder valve. When he fills it, it is full. The places selling by weight are always ripping me off in my opinion. The scale always has dirt on it and is so rusty that it could not be accurate. The place I found when I ran out, sold by weight. While the kid was getting his gloves, I took the weights off the scale and it didn't even move. He claimed it works fine. I made him open the bleeders and watched closely to make sure they were filled. When I asked how much he asked if I was paying cash. When I said yes he asked if I was in need of a receipt. I said no and he told me $30 would cover it. I am pretty sure the cash stayed in his pocket.

According to Worthington, the maker of the vast majority of propane tanks, what I said is true: a 30lb propane tank will hold 30 pounds of propane which is also 7.1 gallons.
Here is the chart with specs for other sizes of tanks:
Steel 4.25 lb. - 60 lb. Specifications

We pay $18 to fill a 30 lb tank at the local Costco by the flat rate charge and last summer I paid $35 in Cape Cod by the gallon ($4.50, IIRC).

purman, those gauges that screw on to the tank just read the vapor or gas pressure. The pressure is constant until the liquid runs out. They give no real indication of how much liquid is in the tank, so they are about worthless.

Another thing to consider, those pre-filled tanks at gas stations, HD and Lowes are 20# cylinders, but they only fill them to 17#. Kind of a rip off, for what they charge for them these days. Good help is hard to find in a country of 300 million employed folks, so they short the cylinders so some minimum wage employee does not put 21 # in a bottle and blow your local HD store to smithereens.

One reason that the cylinders come up short is OPD. The float valve inside the cylinder is designed to stop the filling of the bottle at around 80% of capacity.

How to KNOW ...

I got tired of finding places that only would sell me a tankfull, rather than a topoff. If I've only used fifteen pounds, I don't want to pay for thirty! And I don't trust the little green/red widget / "reserve" switch gizmo on the regulator. (Andy Grove, CEO of Intel has that little book out, "Only The Paranoid Survive!")

So I went "simple" - I only open the valve to one tank. When it's really and truly empty, the gas just stops, stove goes out, etc. Then I run out and close that tank's valve and open the other. Takes all of thirty seconds, and I KNOW I'm operating from a full tank. Next time I fill up the now-empty one, I don't care if they demand I buy a tankfull, 'cause I actually want a tankfull!

Only time this would cause me an issue would be if I were using the furnace (rarely) and it went out in the middle of the night and I had to dash out into the cold and change valves. Hasn't happened yet. Knock on wood.

Oh, if you lift about a zagillion cylinders, you get to the point that you can guesstimate the amount of propane in them pretty well. Lifting bottles that often means a whole lot of Airstreaming, and I'm ready for it!

I'm going to give one of these scales a try. They are about $20-$25.

That thing looks cool.... Might give it a try... but then I have to take the holders of the tanks to do it...

Well it's not like I have anything better to do while hanging out at camp... Another gadget to play with... YEAH>>>
