What is the specific gravity of propane gas?

The specific gravity of a gas is a measure of its density compared to the density of air, which is considered to have a specific gravity of 1. For propane, the specific gravity is approximately 0.51. This means that propane is lighter than air, which is an important safety consideration when working with the gas.

Understanding the specific gravity is essential for various applications, including fuel storage, transport, and ventilation requirements. It is crucial to note that if a gas is lighter than air, it will tend to rise and dissipate in a wide open area, while heavier gases can accumulate in low-lying areas, potentially creating hazardous situations.

The correct information helps ensure safety practices are implemented when handling propane in residential, commercial, or industrial settings. Thus, knowing the correct specific gravity for propane allows for better risk assessment and management strategies.
