Avgas weighs about 6 pounds per gallon.
Aviation gasoline (Avgas) weighs 6 lb. per gallon. Jet fuel (kerosene) weighs 6.84 lb. per gallon.
Aviation gasoline (avgas) has an average weight of slightly over 6 pounds per gallon (6.02) at a Standard Day temperature of 15 degrees C or 59 degrees F.
6.7something depending on atmospheric pressure (colder / higher pressure air, SG gets higher) Avgas 100LL is about 6.0 pounds per gallon at about 60 degrees F. And at sealevel.
AVGAS (aviation gasoline) typically weighs around 6.0 to 6.3 pounds per gallon.
The density of avgas (aviation gasoline) can vary depending on the specific type and temperature. On average, the density of avgas is around 6 pounds per gallon.
It weighs approximately 6.02 lbs per US gallon ( approx 0.72 kg/liter) at "standard temperature" - defined as 15 degrees celsius (59 degrees Fahrenheit). Its density increases to 6.4 lbs per US gallon (0.77 kg/l) at -40 C (also -40 F) and 5.9 lbs per gallon ( 0.7kg/l) at 38 degrees C (100 degrees F). 100LL " avgas " is used in most small aircraft with reciprocating (piston) engines, though some use mogas or ethanol and some new engines are using diesel and/or Jet A. Turbine engines generally use "Jet A" which is more similar to kerosene or diesel. (which is about 7 lbs per gallon)
1.2 to 2 grams per gallon
100LL weighs approximately 6.02 lbs per US gallon
One US gallon is 3.79 L, so it would weigh from 2.69 kg to 2.91 kg, or from 5.92 to 6.42 lbs.One Imperial gallon is 4.55 L, so it would weigh from 3.23 kg to 3.50 kg or from 7.12 lbs. to 7.72 lbs.
As a rough estimate and depending on the grade of fuel and additivies, between 6 and 7 pounds (2.7 to 3.2 kg). Calculations are made on the following figures. Avgas 100LL, 6 lbs for 1 US gallon. Jet A, 6.84 lbs for 1 US gallon. These figures are based on a 60 degree day.
