What is the capacity of a 20 lb propane cylinder?

The capacity of a 20 lb propane cylinder is approximately 4.8 US gallons. This figure comes from the fact that a gallon of liquid propane weighs about 4.24 pounds, therefore, to calculate the volume of propane that a 20 lb cylinder can hold, you would divide the weight of the propane by the weight per gallon. Doing so results in roughly 4.8 gallons of liquid propane.

This makes the capacity significant for individuals and businesses that rely on propane for heating, cooking, or fueling equipment. Understanding the capacity is crucial for determining how often the cylinder will need to be refilled, and it helps in planning for safe storage and transport. Therefore, knowing this capacity is essential for anyone working with propane in any capacity.
