What determines the capacity of an LP-Gas container?

The capacity of an LP-Gas container is primarily determined by weight or volume. This is because the design of propane containers, also known as cylinders or tanks, is based on their ability to hold a specific amount of liquid propane, which can be measured in terms of weight (for example, pounds or kilograms) or volume (such as gallons or liters).

Weight is directly related to how much propane can be stored in the container; the maximum weight will include both the weight of the container itself and the weight of the liquid propane it can hold. Volume is important because it gives a clear indication of the amount of space inside the container designated for holding liquid propane.

While other factors like pressure and temperature can influence how propane behaves within a container, they do not directly determine the container's overall capacity. For instance, the pressure inside the container will change based on temperature, which affects the state of the propane (liquid or gas), but does not affect the physical limits of how much liquid propane the container can hold as defined by its weight or volume specifications.
