Anything is simple once you understand it.  And the same can be said for the capacity and markings of all the different propane cylinders.

Emet came with 2 propane cylinders.  In trying to understand the tank capacity, I was at my wits end.  I finally just took the tanks to the propane refill place down the street and had them filled.  Nothing on the receipt or anywhere else told me how much propane the tank held.

After numerous trips to get the tanks refilled, I finally saw a chart hanging on the fence that converted “WC” to “lbs of propane”.  Well, at least there’s a chart that can found.

We wanted to add another propane tank for our grill.  Aluminum would be the best, but those are terribly expensive.  I was settling on a 10lb steel tank when I happened to find an aluminum tank at the local resale shop.  It was $72 and seemed like a good deal.  Still I had no idea what the tank capacity was.

So, I purchased the tank and set about trying to figure out how much propane it held.

I’ll save you the trouble of having to figure it.  Take the “WC” number (which stands for Water Capacity, because, you know, it’s really helpful to know how much WATER a PROPANE tank holds)  that is stamped on your tank and multiply it by 0.42.  There you go, the amount of propane in pounds that your tank will hold.

TW is “Tare Weight” and is how much your tank weighs when empty.  So, if your tank says “TW 11.0  WC 23.9” then the empty weight of your tank is 11 pounds and it will hold 10 pounds of propane.   When full, your tank should weigh 21 pounds total.
