capacity 100 pounds propane tank

100-pound propane tank holds approximately 23 gallons of propane when it is full. So, if you have a 100-pound propane tank, you would have approximately 23 gallons of propane in it when it’s completely filled.

1. You have a 100-pound propane tank, it holds approximately 23 gallons of propane when it’s full.
   • 100 pounds is the weight of the propane in the tank.
   • 23 gallons is the volume of propane that the tank can hold when it’s full.
   • When the 100 lb tank is empty weighs 67 pounds
   • The total weight of the propane 100 lb propane tank (empty propane tank + propane full) is 167 pounds.
     
     

When the tank is full, it contains 23 gallons of propane.

So, to directly answer your question, a 100-pound propane tank contains 23 gallons of propane when it’s full. This is a standard conversion based on the properties of propane and the capacity of the tank.

Propane Tanks and the 80% Fill Level

Propane tanks, whether they are the common 20-pound cylinders or larger tanks, are designed to be filled to a maximum of 80% of their total volume. This practice is a safety measure recommended by propane industry standards.

The reason for this 80% fill level is to allow space for the propane to expand and contract with temperature changes. Propane is sensitive to temperature, and as it warms, it expands, increasing the pressure inside the tank. Conversely, in colder temperatures, propane contracts, reducing the pressure. By leaving 20% of the tank’s volume empty, there is room for this expansion without causing excessive pressure that could be dangerous.

Additionally, the 80% fill level allows a safety buffer to prevent overfilling, which could lead to potential safety hazards. Therefore, when handling propane tanks, it’s important to follow these guidelines to ensure safe storage and usage.”
