What is the vapor specific gravity of propane?

Explanation:
The key idea is how propane vapor compares in weight to air. Propane’s vapor density relative to air is about 1.5, so the vapor is heavier than air. Because it’s denser, propane vapors tend to stay low, pooling in depressions, basements, or along the floor. This affects how leaks behave and why ventilation and keeping ignition sources away from low spots are critical. So the vapor specific gravity of propane is approximately 1.5.
