Most 20 lb tanks have a tare weight of +/- 17 pounds when completely empty. This means a “full” propane tank should weigh about 37 pounds. There is also a month and year on the collar indicating the date the tank was made. For 20 lb propane tanks, you have 12 years from the manufacture date before the tank must be re-certified with a new date stamped on it.
The re-certification only adds 5 years before having to re-certify again. The cost and inconvenience of re-certifying almost always outweighs the price of a new tank.

Brand new propane tanks may come with air inside and need to be “purged” before the first fill. Some newer tanks, like Bernzomatic, will have a sticker on them saying they don’t need to be purged within 6 months of the manufacture date. Purging requires a special adapter to allow a small amount of propane in.
The pressure then pushes air out of a one-way bleeder valve. Purging may add another $3-4 dollars to a new tank, though some places don’t charge, especially if you buy the tank from them.1 gallon of propane weighs 4.2 pounds A “full” 20 lb cylinder should have 4.7 gallons or propane in it These “20 lb” tanks are designed to take up to 20 pounds of propane.
- You may get a pound or 2 less, depending on the temperature of the tank and surrounding air when the tank was filled.
- Cooler = more propane in, hotter = less in.
- Tanks can actually fit another 20% in the tank, but that extra space is designed for expansion as the temperature rises.
- In very cold winter climates, like Canada, there may be more concern/rules about filling a tank to a complete 20 lbs.
This is because if you leave a tank outside in very cold temps, filled the tank when the tank is cold, and then bring it into a hot basement/garage for a space heater, the gas will expand as the tank warms. With enough of a temperature increase, the tank’s pressure relief value will release a bit of gas.

How much does 1 gallon of propane gas weigh?
What’s the Weight of a Full Propane Tank? – You can calculate the weight of a full propane tank if you know a few pieces of information. First of all, what is the tare weight of the tank? A tank’s tare weight is how much it weighs when it’s empty. That number should be stamped on the tank’s collar.
- It may be written at T.W.
- Secondly, you should know the capacity of the propane tank in gallons.
- Thirdly, you need to know that one gallon of propane weighs 4.2 pounds.
- Multiply the number of gallons the tank can hold by 4.2.
- That will tell you the weight of the propane when the tank is full.
- Then add the tare weight of the tank.
The sum of the tank’s tare weight plus the weight of the propane it can hold when full is the total weight of the full propane tank.
How many gallons is a 20lb propane tank?
20 lb Propane Tank – Dimensions: 1′ 6″ in height and 1′ in diameter. Uses: Propane grills, generators, patio heaters, and other outdoor equipment. To purchase or exchange a 20 lb tank, find a location near you.20 pound propane tanks are often referred to as grill cylinders and hold 4.6 gallons of propane when full. Propane tanks can be placed either above ground or underground.
How much does 1 Litre of propane weigh?
Gas Unit Conversion Background Information Conversely, 1 L of LPG weighs 0.51 kg.
How many gallons are in a 100 pound propane tank?
The Simple Answer – To put it simply, 0.236 gallons = 1 pound of propane. This is true when the propane tank is at a temperature of 60 degrees Fahrenheit. So, 0.236 gallons x 100 pounds = 23.6 gallons. A 100 lb. tank holds 23.6 gallons and weighs 170 lbs. when full. Other Factors As mentioned, there are additional factors that can affect the overall amount of usable propane within the tank.
These include water capacity and tank temperature. Let’s take a closer look at each of these to see how they affect your propane tank supply. Water Capacity Each gas cylinder will have a water capacity number stamped on the collar and will look something like “WC 240.” This is the total mass of liquid – stated in pounds – that a cylinder could hold if filled entirely with water.
However, when filled with propane, gas cylinders can only be filled up to 42% of the water capacity. This is to accommodate for the fluctuations in tank pressure as temperatures change. For this example, 240 (water capacity) x 0.42 (max. capacity) = 100.8 lb.
How heavy is LPG gas?
LPG Density – Is LPG is Lighter than Air – LPG is not lighter than air. LPG is heavier than air. Butane is a bit more than 2 times heavier than air. Butane gas weighs 2.5436 kg/m³ whilst air weighs 1.225 kg/m³. Propane is 1.55 times heavier than air. Propane gas weighs 1.898 kg/m³ vs air at 1.225 kg/m³. (All at 15°C and 1 atm). Specific Gravity of LPG (propane gas) is 1.55 (air = 1.00).
