What is the specific gravity of propane?

Propane's specific gravity is a crucial property that reflects its density relative to air. The specific gravity of propane is approximately 0.6, meaning that it is lighter than air. This characteristic is significant for venting and safety considerations in installations involving gas appliances. When propane leaks, it will rise and disperse in the atmosphere rather than settle, which affects how gas detectors and safety measures are designed in residential and commercial settings. Understanding this property is essential for anyone working with or around propane to ensure proper handling and safety practices.
