What is the weight of a gallon of unleaded gasoline in pounds?

Answer 1

That depends on how much you have! A tanker full of the stuff weighs more than a gallon of it. What you probably meant to ask is how much it weighs per unit volume. In other words, you wish to know its density. The specific gravity of gasoline is about 0.72. That is, it's about 72 percent the density of water. Since a gallon of water weighs 8.34 pounds per gallon, we can easily calculate the density of gas as 6.00 pounds per gallon. By the way, I say "about" above because the density of gasoline varies with temperature.

Answer 2

It depends on the specific density of the gasoline in question. This can usually be found at the pump along with its octane ratings (RON and MON)

But it will fall in the range of 5.8 to 6.5 lbs (Source: U.S. Dept. of Energy. Fuel From Farms)

It is lighter than 1 gallon of water which is approximately 8.33 lbs

Answer 3

The weight of a gallon of unleaded gasoline is approximately 6.3 pounds.

Answer 4

It is about 6.3 pounds.
