 The fuel density is a function of temperature, but for Jet-A at normal temperatures the figure is about 6.7 pounds per gallon.

 And AvGas is 6.0 lbs/gallon if anyone cares. Nick

 Goboeing is correct, 6.7 to 6.8lbs per USG for Jet-A/JP-8.

 A simple formula (for small to medium amounts) that is relatively accurate is 150g = 1000 lbs. 15g = 100 lbs 1500g = 10000 and so on. Start going over 20,000 to 40,000 lbs, and this starts to get pretty far off. The density can change quite a bit depending on temperature. I've seen it as low as 6.55 and has high as 6.85. Mikeclod

 For you Gentlemen who prefer metric... xxx Densities to remember for fuels (weight of 1 liter of xxx at 15 deg. Celsius) - Gasoline density is .69 (690 grams per liter) JP-4 (Jet B) is .78 Jet A is .812 Jet A-1 is .813 xxx Engines burn a weight of a given fuel to operate... so remember this... buy your gasoline for your car at the pump when it is cold (early morning) since you buy gasoline by volume... Example, Jet A fuel when warm might have a demsity of only .80, but could be .82 or .825 when cold... xxx Happy contrails   (s) Skipper

 LanPeru- Remember, this topic was discussed before. You asked this same question in this same forum on Sep. 8, 2002. In case you missed it the first time you asked, here is the answer to your question. You asked "How many USG in a LB of Fuel?" If we're talking Jet-A and use the following: 1 gallon = 6.7 lbs. Then that would equate to: .15 gallons = 1 Pound(lb) of fuel So, there are .15 gallons in a pound(lb) of fuel. And guys, he's asking how many gallons in a pound of fuel, not how much does a pound of fuel weigh. In Jet-A we trust.... Jet-A Gasguy

 Keep in mind that Gallons are a measure of volume while pounds are a measure of weight. So depending on the temperature of the fuel a gallon jug will weight different amounts. Not a big deal with most light aircraft but one of the daily checks on the fuel farm was to measure the height of the fuel in the storage tanks. The difference in the height of fuel in a tank between morning and afternoon temps could be measured in feet on a tank that was not being used.

 BTW the standard in the U.S. is 6.70 lbs per gal. at 60. deg. F. Mikeclod

 How many people are going to answer this question with the same answer???? I think we've covered it. I saw that he asked how many Gallons were in a lb of fuel... if he can't extract that from 6.7lbs/Gallon then he needs to go back to school.
