The weight of a gallon of propane is 4.11 pounds. That is, if you measure it at 77 degrees Fahrenheit.
It’s vital to remember that LPG’s density of 4.11 lb/gallon only applies at normal temperature (77F).
Gases (even liquified gasses like liquid propane) expand at higher temperatures and contract at lower temperatures, as we all know. As a result, when we calculate how much propane weighs per gallon, we must additionally factor in the temperature.
This also explains why the 80 percent maximum filling guideline is necessary when filling propane tanks. In the third section, we’ll utilize this rule to figure out how many gallons a 20-pound propane tank can contain. A 20-pound gas tank can only carry 16 pounds of propane.
To demonstrate that a gallon of propane does not always weigh 4.11 pounds, here are some propane densities at various temperatures:
- At 90F, the density of propane is 4.05 lb/gallon.
- At 80F, the density of propane is 4.09 lb/gallon.
- At 77F, the density of propane is 4.11 lb/gallon.
- At 70F, the density of propane is 4.17 lb/gallon.
- At 60F, the density of propane is 4.20 lb/gallon.
Higher temperatures cause the density of propane to decrease, the volume of propane to increase, and the pressure within a propane tank to rise.
Reduce the temperature by increasing the density of propane, reducing the volume of propane, and lowering the pressure inside a propane tank.
How many gallons does a 20-pound propane tank hold?
Propane Tank, 20 pound Grill cylinders are 20-pound propane tanks that store 4.6 gallons of propane when fully charged.
Does propane have a shelf life?

3. How should old propane tanks be disposed of?
Propane tanks with a volume of 100 pounds or less have a 12-year shelf life from the date of manufacturing. When those 12 years are over, you have the option of replacing the tank or having it inspected for requalification for another five years of use.
4. What is the average lifespan of a tank?
Propane tanks with a volume of 100 pounds or less have a 12-year shelf life from the date of manufacturing.
5. Do all tanks have an expiration date?
Large propane tanks used for residential heating and hot water are restricted by federal container restrictions in most states. According to the legislation, a propane tank can only be filled by the owner or someone authorized to act on their behalf. In practice, this means that the majority of household propane users lease their tank from a fuel supplier, who is responsible for keeping track of the tank’s expiration date.

When a 20-pound propane tank is full, how much does it weigh?
The most popular size of BBQ propane tank is 20 lb. It can also be used to fuel a number of propane heaters and even propane generators.
The dimensions of a 20-pound propane tank are 8 inches length and 4-inches wide. According to the 80 percent safety guideline, a 20 lb propane tank can hold a total of 16 lb of propane.
The empty 20-pound propane tank weighs around 13.5 pounds. Aluminum 20 pound propane cylinders are lighter than steel cylinders.
On average, a full 20-pound propane tank weighs 29.5 pounds. To determine the total, add the 16 pound of propane to the empty weight (13.5 pound) of the 20 pound propane tank.
Overall, a 20 pound propane tank has a lot of BTUs. What is the precise number of BTUs in it?
344,470 BTUs are contained in a 20 pound propane tank. That’s enough to keep a 10,000 BTU/h heater running for several days (34.4 hours, to be exact).
Is it possible to transport a 420-pound propane tank?
Every person who uses a gas grill, runs a generator, or needs propane to heat their home or water has had a tank refilled and loaded into their car.
Are your consumers, on the other hand, doing it correctly? Is this, to be more explicit, being done in a safe manner?
Propane sellers should educate their customers on how to move propane cylinders safely. Let’s go over a few essential items to make sure they’re on the same page before they leave your lot.
In a sedan or SUV, no more than four propane cylinders can be carried at once. The total combined weight of all the cylinders in an enclosed vehicle should not exceed 90 pounds, and no single cylinder shall have a propane capacity of more than 45 pounds. All propane cylinders must be positioned vertically and upright.
A reliable propane tank holder and stabilizer is the safest way to secure a propane cylinder in a vehicle. These tank holders are safe and secure because they fit snugly around the propane cylinder or lock into the cylinder’s foot ring.
Many individuals prefer to transport their milk in a milk box. The cylinders will remain vertical in the crates since they are strong. It’s also acceptable to secure a propane cylinder with rope, twine, or a ratchet strap, but make sure consumers have a sturdy anchor point in their vehicle.
In the back of an open pickup truck or trailer, customers can transport up to 1,000 pounds of propane. The propane cylinders, on the other hand, must be transported vertically and upright.
A 100-pound propane cylinder is heavy, and it should be loaded with caution and the assistance of another person. Because a full 100-pound cylinder can weigh up to 180 pounds, make sure to help customers properly load these into the back of their vehicle or trailer.
Locate the anchor locations once the propane cylinder has been loaded into the back of the truck. Educate your customer on how to secure the cylinder in the vertical, upright position using twine, rope, or other tie-downs at the base, near the foot ring, and at the top. For those who aren’t comfortable making knots, ratchet straps and other tie-downs are available.
Even if forklift cylinders are designed to be used horizontally, make sure clients understand that they should still be delivered vertically. When the cylinder is connected to a forklift, a pin locks the cylinder into a precise position, keeping the pressure relief valve in the cylinder’s vapor area. If the cylinder is transported on its side, it may roll and relocate the pressure relief valve to the bottom of the cylinder’s liquid chamber.
If a client tries to transfer a 100-pound propane cylinder in a sedan or SUV, or if the customer places the tank on its side, take a moment to explain why this is not safe and the dangers that could result from incorrect propane cylinder transportation. Assist them in correcting their error or hold their cylinder until they can return with the appropriate equipment and/or vehicle.
Always complete a thorough pre-fill examination before filling a cylinder for your own and your customers’ safety, and wear personal protective equipment at all times.
Here are a few pointers to remember the next time you sell or fill a propane cylinder. Safety should always come first, and that starts with understanding propane.
