There is a fair amount of variation, but the standard small 16.4oz (1 lb) propane cylinder usually weighs just about a pound when empty (Tare weight, or the weight of the container itself). It is then usually charged with 16oz (by weight) of liquid propane for a total of around 32iz (2 lb).
In Summary
Propane cylinders will have the tare weight or (TW) stamped on the cylinder the tare weight is the weight in pounds of the cylinder when its empty.
17-18 pounds, depending on the manufacturer. The Tare Weight stamped on the bottle . TW 18 would be an 18 pound empty bottle.
1 gal of liquid propane weighs 4.24 lbs. Answer 4.24 lbs X 5 gal = 21.2 LBS
An empty 5 gallon propane tank weighs about 20 lbs. It weights about 40 lbs full.
there are 16oz in a pound.....
I'm guesing about ... 30 LBS!
500 pounds
119 kg
An empty T cylinder weighs approximately 1,400 pounds.
Because it hasn't got any extra mass inside it.
Get a scale appropriate for the amount you wish to weigh. Get a container to put the small objects (screws) in. Weigh the container while it is empty, many modern digital scales allow you to "Zero" the scale with your container on it making for an easy short cut. Write down the weight of the container. Put your screws in the container and weigh the container and the screws. Subtract the weight of the container
About 75 LBS when you weigh the bottom and cardboard incert together
Your cylinder full of gas will weigh more, for it contains the mass of the gas. Some gases, when compressed, such as CO2, are in liquid form, and quite heavy.
There will be a TW on the side of the cylinder this is the tare weight the weight of the cylinder empty. (TW 27) would be an 27 pound empty cylinder. A full cylinder will weigh 30 pounds more than the tare weight.
500 pounds
All propane cylinders will have a TW stamped in the valve protection ring. The tare weight or TW is the weight of the cylinder empty. TW 18 would be a 18 pound empty cylinder. If you weigh a TW 18 cylinder on a bathroom scale, and it weighs 28 pounds there would be 10 pounds of propane remaining in the cylinder.
An empty T cylinder weighs approximately 1,400 pounds.
Gas cylinders weigh about the same whether full or empty.
a typical steel "30 pound" liquid propane tank weighs about 25-28 pounds empty. propane tank markings (on collar) propane weighs about 4.125 pounds per gallon and a "30 pound tank" will hold about 7.5 gallons so a full tank will weigh about 55 pounds or so. Typical recertification stamp: MM XXX YY E MM -> 2 digit recertification month XXX ->3 character Re-qualifier's registration number YY -> 2 digit recertification year E ->States the cylinder has been externally examined WC -> Water capacity of the cylinder. TW -> Tare weight of the cylinder (what the tank weighs empty) ICC, DOT, BTE, CTC or TC -> Specification number eg. TC4BA240 10 89 -> Date of manufacture (October. 1989)
You need a lot of gas to do this, but you start by weighing an empty cylinder. You then put a measured quantity of gas in the cylinder and weigh it again.

Liquid PropaneThere will be a TW on the side of the cylinder this is the tare weight the weight of the cylinder empty. (TW 18.5) would be an 18.5 pound empty cylinder. A full cylinder will weigh 20 pounds more than the tare weight. Even with an OPD valve a 20 pound cylinder will still hold 20 pounds 95% of the time. If you exchange your tank they are only putting 15-18 pounds of propane in a cylinder that was designed to hold 20 pounds. If you have your cylinder refilled make sure they weigh it on a scale as they fill it and put twenty pounds in it the OPD SHOULD STOP THE PUMP AT THE SAME TIME THE SCALE TIPS.(The weight of th filling valve must be added usually 4-5 pounds). Also propane is stored in the tank as a liquid you use the vapor from the top of tank in your grill. As the vapor pressure lowers the liquid will boil into vapor when the vapor pressure is gone the cylinder is completely empty.A 20-pound tank contains about 4.1 gallons of LP, which weighs about 17 pounds. (LP has a specific gravity -- at 25 degrees C -- about half that of water.) The next time I run my tank empty, I'll weigh it. But I would be willing to bet it weighs about four pounds.
Because it hasn't got any extra mass inside it.
Using a pressure guage to determine the pressure of the gas inside, as thepressure decreases you can tell that it is getting empty. Another way is if you know the weight of the empty cylinder weigh the cyleinder and the difference gives you how much nitrogen is in it.
It should weigh 45kg + the TARE weight of 36.6kg for the bottle = 81.6kg when full. The WC (water capacity) of the bottles are 109.8kg and LPG weighs 41% of water = 45kg. This is a good check to see if you are being ripped off by your gas supplier.
