How Many Gallons Are In a 250 lb Propane Tank?
A 250 pound propane tank can hold 59 gallons of propane. 59 gallons of propane is well above the average size tank, making 250 pound propane tanks large.
Most 250 pound propane tanks are used for home appliances and supplemental heating since 59 gallons is quite a lot of propane.
How Do You Calculate How Many Gallons Are In a Propane Tank?
If you are just looking for a quick answer to how many gallons are in a 250 pound propane tank, you have your answer.
That being said, we always recommend doing the math yourself and learning how to do the calculations on your own. That way, you’ll be able to figure out how many gallons are in a different propane tank in the future.
Luckily, calculating how many gallons are in a propane tank is not very difficult. With just some quick conversion, you can calculate the number of gallons in any propane tank.
As a rule of thumb, one pound of propane equals 0.236 gallons.
If you multiply the maximum propane capacity in pounds by 0.236 gallons, you will be able to estimate how many gallons are in a propane tank. Here is the formula to use:
0.236 X capacity of propane tank in pounds = capacity of propane tank in gallons
In the case of a 250 pound propane tank, all you need to do is multiply 0.236 by 250. When you do, you will find that there are 59 gallons in a 250 pound propane tank.
Keep in mind that this formula works for all propane tanks, not just 250 pound tanks.
Temperature: A Changing Variable
One thing to keep in mind is that the calculation of how many gallons are in a propane tank is dependent on temperature.
You probably know that propane tanks are supposed to be stored at 60 degrees Fahrenheit. The reason for this is that temperature affects how the gas molecules act.
If the temperature goes up, the molecules spread out and take more space. If the temperature goes down, the molecules constrict and get closer to one another.
When it comes to propane and tanks, 60 degrees is the ideal temperature. It creates a stable environment that is safe for propane tank usage. Since 60 degrees is the recommended temperature for propane tanks, the 0.236 conversion is based on this temperature.
If the temperature changes, the ratio of gallons to pound changes. We do not recommend changing the temperature of propane because this can be dangerous, though.
Always try to shoot for 60 degrees Fahrenheit. If you do, you will be safer, and the conversions will be easier.
How Much Does a 250 lb Propane Tank Weigh Full?
If you want to know how many gallons are in your 250 pound propane tank, you might also want to know how much a tank weighs when full.
Whenever you calculate how much a full propane tank weighs, you have to add the weight of the propane to the weight of the tank itself.
Obviously, a 250 pound propane tank holds 250 pounds of propane. The tank itself weighs about 483 pounds. To determine how much the tank will weigh when full, you have to add 250 to 483.
When you do the math, you will find that this propane tank weighs about 733 pounds when full. Of course, you’ll want to weigh the tank beforehand because not all tanks are the same.

How Long Does a 250 lb Propane Tank Usually Last?
Calculating how long a propane tank lasts can be difficult. You have to consider the BTU rating of your burner and how long you intend to burn the burner.
The size of the tank also impacts how long the tank will last. Let’s look at an example to show how these factors change the life expectancy of a tank.
Let’s say that your 250 pound propane tank is being used on an 80,000 BTU burner. It will last for about 67.48 hours. If you were to use a burner with a 100,000 BTU rating instead, the propane tank would only last 53.99 hours since this burner is more powerful.
These numbers show that how long your propane tank last ultimately depends on moving factors. You will want to consider your unique burner and situation in order to calculate how long the propane tank will last.
