It probably goes there is no saying, yet a 100 lb. Propane tank is designed to host 100 pounds that propane. Straight-forward, right? Well, not quite… So, how many gallons that propane space there in a 100 lb tank?

Because propane is stored and delivered together a liquid, it deserve to be beneficial to understand what this looks prefer in regards to gallons. If there’s a fairly simple answer, there room a few different components that can influence how numerous gallons room actually in a 100 lb. Tank.

You are watching: How many gallons is 100 pounds of propane

The straightforward Answer

*

To placed it simply, 0.236 gallons = 1 pound of propane. 

This is true once the propane tank is at a temperature that 60 levels Fahrenheit. 

So, 0.236 gallons x 100 pounds = 23.6 gallons.

A 100 lb. Tank holds 23.6 gallons and weighs 170 lbs. As soon as full.

Other Factors

As mentioned, there are extr factors the can influence the all at once amount that usable propane in ~ the tank. These incorporate 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 actually a water volume number stamped on the collar and will look something like “WC 240.” This is the complete mass of fluid – proclaimed in pounds – the a cylinder could hold if filled completely with water. 

However, once filled with propane, gas cylinders deserve to only it is in filled approximately 42% of the water capacity. This is to accommodate for the fluctuations in tank press as temperature change.

For this example, 240 (water capacity) x 0.42 (max. Capacity) = 100.8 lb.

So our tank have the right to actually host a maximum of 100.8 lb when filled.

As discussed above, we understand that each lb. Propane is 0.236 gallons.

This way that 0.236 gallons x 100.8 pounds = 23.789 gallon propane.

Again, this doesn’t do a huge difference, but it have the right to still be a element to think about when deciding what size of tank to use.

How Temperature influence Tank Pressure

*

Propane does no sit unaffected in ~ propane tanks. The optimal ambient temperature (which was assumed in the instance above) is 60 degrees Fahrenheit. At this temperature, a tank that has actually been to fill would develop a reading of about 40% ~ above a tank gauge. 

As temperatures rise, the tank gauge reading will go up. It’s quiet the very same weight of propane in the tank – the molecules have actually just become more spread out. 

The reverse happens when temperatures drop, so don’t be surprised once that analysis goes down. This is not due to the fact that there is less usable propane in the tank – the propane has actually just become an ext dense or compact, and also the volume has decreased. The colder the temperature, the much more the levels will change. 

The lower pressure can reason tanks to avoid working properly. Maintaining tank push up might require much more frequent refills; even when over there is tho “usable” propane in the tank, the volume is no high enough and extr propane should be added to lug tank pressure ago up. 

How deserve to I store My Propane in ~ the best Temperature?

Constantly making a trip to gain a tank refill can be costly and frustrating. Luckily, over there is another way to save your tank working nicely v plenty that propane at the ready when you space – Propane Tank Heaters. 

Propane tank heaters effortlessly transfer warm to the tank, raising the BTU (British thermal Energy) the the propane. In basic terms, this heat power works by transferring heat from one thing (the tank heater) to an additional (the tank) – boosting the motion of that molecules and also keeping it at optimal functioning temperature. 

A well-made heater will save you the trouble of making time-consuming, not to point out expensive, refills by raising your tank temperature and, consequently, your all at once tank pressure. This kind of heater is a safety-certified electric blanket that wraps approximately the whole surface of her tank, no issue what dimension tank the is. The absolutely the “no-hassle” strategy to temperature regulation, allowing you to usage every gallon the propane within the tank.

 If you frequently use propane during cold weather months, a tank heater is definitely worth checking out!
