It depends on specific gravity of Jet A fuel. It can be calculated by multipling specific gravity of fuel by 2.2.
1.78 pounds
There are 2 different fuel types but Jet A is the most common. Jet A / Jet A-1: 0.775 to 0.840 kg/L Jet B: 0.751 to 0.802 kg/L
410 lbs
how much does a jet ski weigh
6.667 lbs
The weight of Jet A, also known as aviation fuel depends on temperature and density. A rough estimate is that one gallon of Jet A approximated to 6.79-pounds.
Its density
a bunch
12 pounds
It varies by some small degree according to temperature (and by the batch) but for all practical purposes Jet-A weighs 6.8 pounds per gallon.
The final quarter 2014, the average cost of jet fuel was about $2.85 per gallon. A Boeing 777 holds about 51,585 gallons of jet fuel.
Depends on the jet, they hold about one 25th of a Boeing 737's fuel.
