Fuel weight
Volume ↔ weight at the FAA standard figures — avgas 6.0 lb/gal, Jet A 6.8 lb/gal (FAA-H-8083-1B ch 3): 50 gal of avgas is 300 lb on the weight-and-balance form.

How this is computed
Labeled assumption — Uses FAA standard weights (avgas 6.0, Jet A 6.8 lb/gal, FAA-H-8083-1B ch 3) — not measured density. Real fuel density varies with temperature; use metered figures when weight is critical.
