The weight of 100LL avgas (100 octane low-lead aviation gasoline) depends on its density, which can vary slightly with temperature. On average:
100LL avgas weighs approximately 6 pounds per gallon (2.72 kilograms per gallon) at standard temperature (15°C or 59°F).
The weight of aviation gasoline (avgas) depends on its type and temperature. Here’s a general breakdown:
100LL Avgas (100 Octane Low Lead)
Standard Weight: Approximately 6 pounds per gallon (2.72 kilograms per gallon) at standard temperature (15°C or 59°F).
Density: Around 0.72 kilograms per liter (720 grams per liter).
Factors Affecting Weight
1. Temperature:
As temperature increases, avgas expands and becomes less dense, reducing its weight per gallon.
Conversely, at lower temperatures, it becomes denser and heavier per gallon.
2. Specific Gravity:
The specific gravity of 100LL avgas is roughly 0.72 compared to water, which weighs 8.34 pounds per gallon.
