The weight of a gallon of Jet A fuel, the most common type of aviation kerosene, is approximately 6.7 pounds or 3.0 kilograms. This value can fluctuate slightly based on temperature and fuel composition variations.
Accurate fuel weight determination is crucial for flight safety and efficiency. Knowing the precise weight influences aircraft performance calculations, including range, takeoff speed, and payload capacity. Historically, imprecise fuel measurements posed significant risks, highlighting the need for standardized procedures and accurate weight estimations. This understanding facilitated advancements in aircraft design and operational efficiency.
