Depends on the plane, and the type of fuel.
Aviation gasoline (Avgas) weighs 6 lb. per gallon. Jet fuel (kerosene) weighs 6.84 lb. per gallon.
Depends on what airplane the jet engine is mounted in.
Jet fuel weighs 6.8 lbs per gallon.
btu per pound * pounds per gallon OK, it sounds as if you know the value of fuel in oil btu per pound.Now find out how much a gallon of fuel oil weighs and multiply the btu value x that weight in pounds and that is the value per gallon. Or simply, diesel fuel is #2 fuel oil which contains 140,000 btu per gallon.
That depends on the price of fuel per gallon.
Divide a gallon by the miles per gallon. 1/mpg=amount
You need to know the price per gallon and also the miles per gallon your car can achieve. Then the cost per mile is the dollars per gallon divided by the miles per gallon. The answer is in dollars per mile (in the UK use pounds instead). So with fuel at $1 per gallon, and car that does 20 mpg, the fuel cost is $1 / 20 per mile, or 5 cents per mile.
6.84 LBS PER GALLON
6.84 pounds per gallon
1 Gallon of gasoline weighs 6.152 lbs.
The weight of a gallon of Avjet fuel can vary based on the specific gravity of the fuel. On average, jet fuel weighs around 6.7 pounds per gallon.
