When calculating the heater ratings, we all needed different sizes of propane tanks to properly size the heater units. This would range from stating:
Finding all of these propane tank specs wasn't easy. It was even difficult to find the dimensions of the most common 20-pound, 100-pound, 250-gallon, and 500-gallon propane tanks. If you've googled a bit about propane tank sizes, you've probably had a similar experience.
We didn't find any website resource where you want to list all propane cylinders:from a 1 lb propane bottle to the massive 2,000 gallon underground propane tank– with their sizes; mainly dimensions and tare weight (empty weight).

In many cases you will also need to convert pounds of propane to gallons of propane. You couldCheck here how much a gallon of propane gas weighs in detail; We'll use a simple one1 gallon of propane equals 4.25 pounds of propaneconversion.
Example 1:How many gallons of propane are in a 100 lb tank? 100 pounds contains 80 pounds of propane. Since 4.25 lbs of propane equals 1 gallon, that means a 100 lbs propane tank contains18.82 gallons of propane.
Example 2:How many gallons of propane are in a 20 lb tank? The 20 lb tank holds 16 lb of propane. That means a 20 pound tank contains3.76 gallons of propane.
Now let’s focus on the key specifications of the 5 most common propane cylinder sizes. Let's start with the 3 major sizes of residential propane tanks:
Dimensions, weight, BTU of 100 gallons of propane
|Dimensions (LxWxH):||50x28x28 inches|
|propane content:||80 gallons|
|Tank leather weight:||212 pounds|
|Full tank weight:||552 pounds|
|How many BTUs:||7.320.000 BTU|
|You can generate 10,000 BTU/hr for:||30 days and 12 hours|
100 gallon is one of the most common horizontal residential propane tank sizes. It's not necessarily underground; Most homeowners keep it in the basement or garage.
The dimensions of the 100 gallon propane tank are 50 inches wide (4 ft 2 in) and 28 inches in diameter (i.e. 2 ft 2 in wide and high).
You can fill a 100 gallon tank with a maximum of 80 gallons of propane. That's the 80% rule; If 100% full, the tank would pose a high temperature safety hazard.
How much does a 100 gallon propane tank weigh when empty? 212 pounds on average. Of course it depends on the metal the tank is made of; For example, 100-gallon aluminum propane tanks are lighter than steel tanks.
How much does a 100 gallon propane tank weigh when full? 552 pounds on average. Here you need to take the tare weight of the empty tank and add the propane weight.
1 gallon of propane weighs 4.25 pounds. You can put 80 gallons of propane in a 100 gallon tank, that's an additional 80 × 4.25 = 340 pounds. The full 100 gallon tank weighs 212 lbs + 340 lbs = 552 lbs.
Now for the calculation of the BTU content. Here is the simple conversion we can use:
1 Gallone Propan = 91.500 BTUs
How many BTUs are in a 100 gallon propane tank?
We need to multiply 80 gallons of propane by 91,500 BTUs:
80 gallons × 91,500 BTU per gallon = 7,320,000 BTU
There are 7,320,000 BTUs in a 100 gallon propane tank. If we used this tank to generate 10,000 BTU/hr of heat output, we could run that heat output for about 1 month (30 days and 12 hours to be exact). You couldCheck how long a 100 gallon propane tank lasts here.
Dimensions, weight, BTU of 250 gallon propane
|Dimensions (LxWxH):||92x30x30 inches|
|propane content:||200 gallons|
|Tank leather weight:||483 pounds|
|Full tank weight:||1,333 pounds|
|How many BTUs:||18.300.000 BTU|
|You can generate 10,000 BTU/hr for:||76 days and 6 hours|

If you fill a 250-gallon tank completely with propane, it weighs 1,333 pounds. The 200 gallon propane adds 850 pounds to the weight of the 250 gallon propane tank.
How many BTUs are in a 250 gallon propane tank?
18,300,000 BTUs total. You can calculate the BTU content of a 250 gallon tank by dividing the max volume of propane (200 gallons) with 91,500 BTUs per gallon propane energy content.
Holding 18,300,000 BTUs, a 250 gallon propane tank can run a 10,000 BTU/hr heater or stove for 76 days and 6 hours. You couldCheck how long a 250 gallon propane tank lasts here.
Dimensions, weight, BTU of 500 gallons of propane

How much does a full 20 lb propane bottle weigh?
The full 20-pound propane tank weighs an average of 29.5 pounds. You must add the weight of 16 pounds of propane to the empty weight (13.5 pounds) of the 20 pound propane tank to get the total.
Overall, a 20-pound propane tank contains a large amount of BTUs. Exactly how many BTUs does it contain?
The 20-pound propane tank holds 344,470 BTUs. That's enough to power a 10,000 BTU/hr heater for more than a day (34.4 hours to be exact).
100-pound propane tank dimensions, weight, BTU
|Dimensions (LxWxH):||48 × 14.5 × 14.5 inches|
