When determining the right propane tank size for your needs, understanding its capacity in gallons is crucial. Propane tanks come in various sizes, each suited for different applications, ranging from small portable units for camping to large stationary ones for home heating. Knowing the number of gallons a propane tank can hold helps you plan for refills, manage fuel consumption, and ensure you have enough propane for your intended use.
Propane tanks are measured in terms of water capacity and propane capacity, with the latter being about 80% of the total tank volume. This standard is in place to allow for the expansion of propane gas, as significant temperature changes can affect its volume. Therefore, when a propane tank is said to be "full," it is usually filled to 80% of its total capacity to ensure safety and efficiency. Understanding this concept is key to answering the question, "How many gallons in a propane tank?"
The size of a propane tank is typically indicated by its weight in pounds, such as a 20-pound or 100-pound tank, but it can also be noted by its gallon capacity, like a 100-gallon tank. Different sizes serve different purposes, and the right choice depends on your specific needs, whether for residential, commercial, or recreational use. In this article, we will explore the various sizes of propane tanks, how their capacities are calculated, and provide a comprehensive guide to help you determine the best tank for your requirements.

Understanding Propane Tank Capacities
Propane tanks, whether small or large, are designed to store liquefied petroleum gas (LPG) safely. Understanding their capacity is essential for both safety and utility. Propane is stored in a tank as a liquid and vaporizes into a gas when released, which is what we use in our appliances.
The capacity of a propane tank is often expressed in gallons, but it is crucial to remember that the tanks are not filled to their maximum volume. This is because propane expands when heated, and filling a tank to its brim could lead to dangerous pressure levels. Therefore, tanks are filled to about 80% of their total capacity, a practice known as the "80% rule."
Why Is the 80% Rule Important?
This rule is crucial for safety. Propane expands at a rate much higher than water, so an allowance must be made in the tank for this expansion. Without this space, the pressure could increase to unsafe levels, potentially causing a leak or explosion. Thus, understanding the capacity of propane tanks, including the 80% rule, helps in proper usage and maintenance.
Measuring Propane Capacity
When discussing propane tank sizes, you might encounter terms like water capacity (WC) and propane gallons. Water capacity refers to the total volume a tank could theoretically hold if filled with water, while propane gallons refer to the actual amount of propane the tank can store, accounting for the 80% rule.
Common Propane Tank Sizes
Propane tanks come in various sizes, each serving different needs. From small tanks used for grilling to large tanks used for heating homes, understanding these sizes helps in selecting the appropriate tank for your application.
Portable Propane Tanks
Portable tanks, such as 5-pound, 20-pound, and 30-pound tanks, are commonly used for grills, RVs, and small appliances. These tanks are easy to transport and refill, making them ideal for temporary or mobile use.

Stationary Propane Tanks
Larger stationary tanks, like 100-gallon, 250-gallon, and 500-gallon tanks, are used for residential heating, cooking, and water heating. They are installed on-site and connected directly to your household's propane system, providing a consistent fuel source.
Calculating Propane Capacity
Calculating the propane capacity of a tank involves understanding both its physical dimensions and the 80% fill rule. This calculation ensures that you know exactly how much propane your tank can store safely.
Steps to Calculate Propane Gallons
- Identify the size of your tank (in pounds or water capacity).
- Convert this size to gallons using a conversion factor (1 pound of propane equals approximately 0.236 gallons).
- Apply the 80% rule to determine the safe fill level.
Example Calculation
For a 100-pound propane tank, the calculation would be as follows:
- 100 pounds x 0.236 gallons/pound = 23.6 gallons
- 23.6 gallons x 80% = 18.88 gallons (safe fill level)
How Many Gallons in a 20-Pound Tank?
A 20-pound propane tank is one of the most common sizes, often used for grilling and small appliances. Understanding its capacity helps in planning refills and usage.
Capacity of a 20-Pound Tank
A 20-pound tank can hold approximately 4.7 gallons of propane when filled to 80% capacity. This makes it ideal for short-term use and easy transport.
Applications of 20-Pound Tanks
These tanks are perfect for:
- Barbecue grills
- Camping stoves
- Portable heaters
How Many Gallons in a 100-Pound Tank?
A 100-pound propane tank is larger and suitable for more extensive applications, such as heating small spaces or fueling larger appliances.
Capacity of a 100-Pound Tank
This tank can hold approximately 23.6 gallons of propane, reduced to 18.88 gallons with the 80% fill rule, ensuring safety and efficiency.
Uses for 100-Pound Tanks
Common uses include:
- Space heaters
- Water heaters
- Backup generators
How Many Gallons in a 500-Gallon Tank?
The 500-gallon propane tank is widely used in residential and commercial settings, providing a steady supply for heating and other large-scale applications.
Capacity of a 500-Gallon Tank
When filled to the 80% rule, a 500-gallon tank can safely store up to 400 gallons of propane. This capacity suits long-term use without frequent refills.
Applications for 500-Gallon Tanks
These tanks are typically used for:
- Home heating
- Commercial kitchens
- Industrial uses
Residential vs. Commercial Propane Tanks
Propane tanks are used in both residential and commercial settings, but there are differences in terms of size, usage, and installation.
