How many gallons of lp in a 100 pound tank

There are 0.236 gallons in one pound of propane. Therefore, in a 20-pound propane tank. there are 4.72 gallons of propane (20 lbs x 0.236 gallons per lb = 4.72 gallons).

The table below provides the gallons of propane in common propane tank sizes. If your propane tank size is not listed below, simply multiply the tank size in pounds by 0.236 to determine the gallons of propane in a given tank.

Tank Size Gallons of Propane in Tank
20 lb 4.72
30 lb 7.08
33 lb 7.788
40 lb 9.44
50 lb 11.8
100 lb 23.6

The right tank size also depends on how much propane gas your appliances use. In addition to the furnace, remember that dryers use 15-25 gallons of propane per year, gas ranges 25-50, and hot water heaters between 200-300 gallons depending on the size of your family.

Things to Consider When You Choose Your Propane Gas Tank Size

Propane doesn’t go bad with time

If you have a good place to store your propane tanks, you could hold the gas for many years before using it. This is a huge advantage over diesel and other standard fuels that eventually go bad in storage. Although the pressure seals of propane tanks can become faulty, this is less likely if they are stored correctly.

How often you use propane and what you use propane for

There are two schools of thought regarding the right propane tank sizes. Generally, you’ll use your tank only during the winter, and it’ll sit idle all through the warmer months, so you can save on the cost of gas by choosing the smallest tank that will meet your needs. This is common when you have limited space for your tank or can’t use underground storage to conserve space.

On the other hand, if you have a large budget or like being “prepared for anything,” a larger tank may be appropriate. Homeowners who choose to buy a larger tank will be able to fill up on propane when prices are at their lowest and might not have to fill up again during the winter.

Square footage of your home and the total BTU of propane gas appliances

Using the square footage of your home and the total BTU load of all your appliances, you may be able to get a good estimate of your average propane use in a year. This is becoming easier as more appliances integrate “smart” technology to measure and reduce your usage. Generally speaking, though, a close estimate will be fine for most homes.

You should upgrade your propane tank size if your usage increases

Propane makes it easy for you to scale your usage up or down as your needs change. Don’t be too worried about making the “wrong” choice. After the first year, you’ll have a much clearer idea of your needs and can refine your heating approach to save even more money.

You have probably heard propane referred to in pounds: 20 lb tank, 33 lb tank, 100lb and so on. That refers to the weight of the tank when it’s full of propane. But understanding how much propane that is can be confusing. This also makes it difficult to know how big a tank you will need. After all, we typically measure liquids in gallons, not by weight.

To help you better understand what size tank you need, here is a breakdown of common propane tank weights/sizes, how many gallons are in each, and common uses of each.
