Question

How many pounds does 1 gallon of jet fuel weigh??

Answer 1

I dont know if all fuels are the same, but a gallon of gas is about just over 6 lbs

Answer 2

Between 6.4 and 6.8 pounds per gallon.

Answer 3

6.7

Answer 4

Density at 15 °C (60 °F): 0.775–0.840 kg/L

for Jet A fuel

Answer 5

Normal JET A weighs 6.7 lbs./gal

Other fuels with different density weigh out  different.

Ranges from 6.4 lbs. to 6.8/gal  roughly

Answer 6

The standard is 6.79 lbs/gal.  One of the cheats I used to regularly use when a calculator wasn't available and a pilot requested his fuel in pounds, (taught to me by another jet pilot,) "divide by ten, add half again."

If I take a Hawker pilot, (ex-army,) who used to routinely request overwing fueling in pounds, as an example, and the thousand pounds he thought he'd burn on a short flight,... 1000/10= 100. I add half of that number and I come up with 150 gallons of fuel. I divide by 2 and I'm at 75 gallons each wing.

Using the calculator, if I divide 1000/6.79, I'm showing 148 gallons. My guesstimation was only off by 2 gallons; If that's going to make a difference, the pilot has problems before the engines are started.

There are temperature/volume compensators for dispensing units, (those were a b*****d to calibrate,) available from Veeder-Root, due to the fact that heavier fuels react differently to temperature changes.

Unless you live in a rapidly changing climate, 6.79 pounds per gallon is what Exxon, Cheveron and Gammon tech trained me to expect and use to make calculations. Like I said before, if an additional gallon or two of fuel makes a difference, you're already screwed.

Answer 7

Jet fuel weighs approximately 62.5% of the weight of water.

water weighs 8lbs/gal, do the math for the approximate weight.

i n order to find the exact weight of jet fuel, you have to know the API Gravity (The American Petroleum Institute gravity,)because each "batch" of jet will vary somewhat in it's API, which is normally somewhere around a 45.0. You can then refer to Table 3 of the ASTM Petroleum Measurement Tables and find the exact lbs./gal of the fuel in question.

Answer 8

The same as a gallon of milk, or water.

Answer 9

It changes depending on temperature, but generally 6.7 pound/gallon is what we use to ballpark it.
