Few human being know ns was a typical propane filling an equipment in my high college days at Taylor Hardware. As a result, I know a few things around tank tare weights (an north tank"s weight) and other propane lingo.

You are watching: How much does liquid propane weigh per gallon

For the last 7 years I had my trusty Weber grill hooked right into a 500 gallon underground tank in ~ the home in Taylors. When I moved previously this year come an all-electric residence I had to switch ago to a conventional 20 lb BBQ grill tank. I also considered 30, 33, 40, 60, and also 100 pound cylinders, to protect against refilling as often. I found that brand-new 30 or 33 lb cylinders space at least twin the price of a 20 lb, and also finding lightly provided ones ~ above Craigslist wasn"t happening.

I choose up a new 20 lb tank at the house Depot because that 29.97, minus 10% off competitors coupon and also a 10% discount top top a gift card purchased on eBay. (Costco sells tanks for 28.99 compared to Amazon"s approximately $45). Now, where to to fill it?

A tiny About Propane Tanks

These "20 lb" tanks space designed come take as much as 20 pounds of propane. Girlfriend may acquire a pound or 2 less, depending upon the temperature that the tank and surrounding air once the tank was filled. Cooler = much more propane in, name is = less in. Tanks have the right to actually fit one more 20% in the tank, yet that extra space is design for development as the temperature rises.

In an extremely cold winter climates, favor Canada, there may be an ext concern/rules about filling a tank come a finish 20 lbs. This is because if you leaving a tank outside in an extremely cold temps, fill the tank once the tank is cold, and then bring it into a hot basement/garage because that a space heater, the gas will broaden as the tank warms. With enough of a temperature increase, the tank"s push relief worth will relax a little of gas. This would be much less of an concern if the relief worth were bleeding to exterior air.


All propane tanks have a "tare weight" or "T.W." stamped top top the collar of the tank. For a grill sized tank you just calculate the tare weight + 20 lbs, and that"s exactly how much the tank should weigh once it"s full. Most 20 lb tanks have actually a tare load of +/- 17 pounds when completely empty. This means a "full" propane tank should weigh around 37 pounds.

There is also a month and year ~ above the collar indicating the date the tank was made. For 20 lb propane tanks, you have actually 12 year from the to produce date before the tank should be re-certified through a new date stamped ~ above it. The re-certification just adds 5 years before having to re-certify again. The cost and also inconvenience that re-certifying practically always outweighs the price that a new tank.

Brand brand-new propane tanks may come with air inside and also need to be "purged" before the very first fill. Some more recent tanks, choose Bernzomatic, will have a sticker on them speak they don"t must be purged within 6 months of the produce date.

Purging calls for a distinct adapter to enable a tiny amount that propane in. The press then pushes air out of a one-way bleeder valve. Purging may include another $3-4 dollars to a new tank, though some locations don"t charge, especially if you buy the tank native them.

The math on Refills in ~ Costco

Internet searches imply the following:

1 gallon that propane weighs 4.2 poundsA "full" 20 lb cylinder should have 4.7 gallons or propane in it

I called around and also the neighborhood U-Haul ar wanted $16 for a refill. I remember Costco has actually a authorize for $9.99 refills. I thought I was gaining a great deal, but it transforms out ns pretty much obtained no deal.


Costco in Greenville, SC is a little bit deceiving because they first hand you a slip that claims "20 lb cylinder". Once you pay within the receipt says "20lb PROPANE", and the filling print out claims "Cylinder: 20S lbs." The only defense is that the filling publish out is honest and also says "3.6 gallons". However, nobody knows turn off the top of your head that a propane tank is an alleged to have 4.7 gallons come be taken into consideration "full". By speak 3.6 gallons, they room masking the fact that they placed in 75%. If they want to it is in upfront they"d speak "we will put 15 lbs the propane right into this 20 lb cylinder".

This way Costco puts in 15 lb of propane.

3.6 gallons / 4.7 gallons = 75% that the regular fill.

or, said an additional way

(4.2 pounds/gallons) * (3.6 gallons) = 15 pounds

The indigenous on the internet forums is the the Blue Rhino and also AmeriGas comparable exchange services put in 75%, or 15 lbs.

If you execute the mathematics on Costco, it"s actually no a negative price. It"s in line, if not cheaper, 보다 paying $16 for a full 20 lbs. Though, Costco"s usage of the "20 lb" expression is unfortunate. Ns think their motivation is to have a cheaper price, therefore members think lock are obtaining a an excellent deal. Plus, by just filling 75% they do members come back more often, and also go inside to shop while they wait.

I likewise assembled the grills at Taylor Hardware. Weber Grills were by far the finest we sold. Reasonable care and a covering will quickly give your Weber grill 10-20 years of life. You deserve to buy various other cheap brands and they will have steel components that rust out in 2-3 years. You have the right to buy a fancy looking stainless steel brand from home Depot and it will likely not rust, however it will chef unevenly or the manage or wheels will certainly break off and also you"ll be earlier to the store in 5 years for a brand-new grill.

Bonus - next Burners

I also helped offer the BBQ grills. We marketed a couple of with side burners, however we never ever pushed them. I recall plenty of conversations through customers who had paid an ext for a next burner in the past and also never used it, regardless of their ideal intentions. Possibilities are the you will usage the next burner as soon as or twice, therefore don"t spend the money uneven you are absolutely sure you"re walk to usage it
