How Much Does a Gallon of Propane Weigh?

Propane is a commonly used fuel that is known for its versatility and efficiency. It is commonly used for heating, cooking, and even as fuel for vehicles. If you are considering using propane, you may be wondering how much a gallon of propane weighs. In this article, we will explore the weight of propane and answer some frequently asked questions about this popular fuel.

The weight of a gallon of propane can vary slightly depending on factors such as temperature and pressure. However, in general, a gallon of propane weighs approximately 4.2 pounds (1.9 kilograms). This weight is based on propane at a temperature of 60 degrees Fahrenheit (15 degrees Celsius) and a pressure of 14.7 pounds per square inch (psi). It is important to note that propane is stored in its liquid form under pressure, and when released, it vaporizes and becomes a gas that is used for various applications.

Propane tanks are commonly available in different sizes, ranging from small portable tanks to large stationary tanks. The weight of the propane tank itself should also be taken into consideration when determining the total weight of propane. For example, a typical 20-pound propane tank weighs around 40 pounds (18 kilograms) when full.
