How much does a gallon of gasoline weigh?
How much does a gallon of gasoline weigh? How much does a gallon of diesel weigh? These questions are important when you are trying to decide what you should use for your car, tools, and equipment, or for your emergency power supply and yes we will be assuming that you are interested in the weight of gasoline and not just any type of gas (e.g. oxygen).
So, the answer here is of course relative as weight is contingent on other factors. But, to give you an average figure, a U.S. gallon of gasoline weighs about 6 pounds according to the Science and Technology Desk Reference. For comparison, a U.S. gallon of water weighs about 8.4 pounds.
To give you a clearer idea of how much gas weighs and why anyway let’s go over the basic formula together.
The quality requirement of gasoline, as specified by ASTM D4052 (The Standard test method for density, relative density, and API gravity of liquids by Digital Density Meter), is indicated to be between 0.71 and 0.78 g/cm3 in a standard density measurement of 15°C (59°F).
So, if we use that 1 gallon equals 4 qts; 1 liter equals 1.1 qt, and 1000 ml equals 1 liter with a density of 0.78 g/mL (the maximum) we will come up to 2836 grams. And because 454g = 1 lb, this gives us a weight of 6.2 U.S. pounds for a gallon of gasoline. If we were to get a more average density than 0.78 g/mL we would have gotten exactly 6 pounds.
Another way to calculate it is by going through the Imperial gallon figure and converting it to U.S. gallons. So, if 1 Imperial gallon of water weighs 10 pounds and we take a gasoline density of 0.73 g/mL this time, this means that one Imperial gallon of gasoline weighs 7.3 pounds. And since 1 U.S. gallon is equal to 0.83 Imperial gallons, we can simply multiply 7.3 by 0.83 and we will get the weight of a gallon of gasoline to be 6.059 pounds.
We can also look at the metric values. To do this we will have to start with the fact that 1 liter of water weighs 1 kilogram. If we factor in specific gravity of 0.72 then for U.S. Gallons we will get 3.78 liters and for Imperial gallons, we will get 4.54 liters. This is an easy calculation to make because the base relationship of the Imperial or Metric values is based on water with a specific gravity of 1. So it is easy to recall it as 1 Kg a liter or 10 pounds a gallon.
As for diesel, it has a density of roughly 0.832 g/cm^3 or 0.834 kg/L Gallon of diesel can be calculated to have a mass of 6.943 pounds per gallon which is a bit heavier than gasoline... So, a U.S. For the Imperial system, the number is 8.338 pounds per Imperial gallon.

How much does a gallon of petrol weigh?
A US gallon of gasoline (petrol) weighs about 6 pounds (2.7 Kg.).
A UK gallon would weigh about 20% more.
According to the Science and Technology Desk Reference, the weight of a gallon of common fuel (such as gasoline) is six pounds (2.72 kgs). A gallon of water, on the other hand, weighs about 8.4 pounds (3.8 kgs)
1 gallon - 3.78 liters
Specific gravity of crude oil - 0.87
Gasoline / Petrol specific gravity - 0.7
Weight = 3.78 liters * 0.7 = 2.64 kgs approx.
= 3.78 * 0.8 = 3.024
The specific gravity of a liquid is like the density of a solid object.
In this case, the petrol specific gravity is taken as 0.7 whereas it varies slightly based on the purity aspect from 0.7 to 0.74. Some additives get added to petrol to impro

How much does a gallon of petrol weigh?
The exact weight of a gallon of petrol (aka gasoline) varies with its composition but is roughly 6 lbs per gallon. Note that water is about 8.3 lbs per gallon, so gasoline will float on water. In pre-flighting my propeller-driven aircraft, I would drain any water in the tank by opening a valve on the underside of the wing tanks.
BTW: The gallons here are U.S. Customary ones; the Brits have a larger gallon.
It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn't come from the gasoline itself, but from the oxygen in the air.
A gallon of water weighs 8.3454 lbs; Gasoline is a complex mixture but we can get a good approximation by using the data for isooctane ( 2,2,4-trimethylpentane) which is a standard for the rating of gasoline. Isooctane has a rating of 100 octanes for comparison, The specific gravity of isooctane is 0.692 thus the weight of a gallon of isooctane = (0.692)(8.3454) = 5.7751 lbs
I assume by gas you mean gasoline (or petrol in many parts of the world), not just any gas.
The weight of gas varies with the particular blend, but 6.3 to 6.4 pounds per gallon should be close enough.
Roughly 6.0 pounds, but it varies considerably by specific blend. For example, if it contains alcohol (which it often does), it will weigh differently than if it contains all petroleum-based compounds. Too, if it does contain alcohol then it may also contain a like quantity of water, which drives up the weight per gallon.
6.25 pounds per gallon of gasoline, diesel is generally 6.8 pounds per gallon.

Would everyone please go to this website: Volume to Weight conversions for common substances and materials
There are all sorts of conversions easily obtainable with very good accuracy. They use a specific gravity of about 0.75, so their US gallon of water weighs 8.3454* lb, while the US gallon of “gas” weighs 6.2499 lb. Divide 6.2499/8.3454 = 0.7489.
Let’s call it 6.25 lb/US gallon or 7.49 lb/Imp gallon. For metric users that would be 0.7489 kg/liter. For those who like to mix units, about 1.65 lb/liter.

How much does a gallon of gasoline weigh?
Gasoline is around 0.74 times the density of water (but varies between refineries and lots). Water is about 8.34 lb/US gallon so 6.17 lb.
The specific gravity of gasoline at 60° F is 0.739.
The weight of 1 gallon of water at that temperature is 8.34 US lbs.
Therefore 1 gallon of gasoline at 60° F weighs 6.16 US lbs.
According to Dr. GOOGLE:
The quality requirement of gasoline is specified by ASTM D4052 and is obliged to indicate 0.71～0.78 g/cm3 in density measurement (15°C) specified by ASTM D4052.
Using 1 gal = 4 qts; 1 L = 1.1 qt; 1000 ml = 1 L, and a density of 0.78 g/mL.
I came up with 2836 g. Since 454 g = 1 lb, this gives a weight of 6.2 pounds for a gallon of gasoline.
If you are referring to gas (e.g. oxygen), one mole of gas occupies 22.4 L at STP. Using the molar mass, you could find the mass in the 22.4 L and convert it to lbs/gal.
Depends on the gas. 22.4 liters of gas weighs approximately its molecular weight in grams, 32 for oxygen, 146 for SF6, and 2 for hydrogen. A gallon is 4.54 liters, so a gallon of O2 weighs ~6.5g, SF6 29.6g, and H2 0.4g.

US gallon or imperial gallon. My guess is you mean US gallon as America is the only country that doesn’t use the metric system.
The weight of different fuels varies. The gas used for autos generally weighs about 6.6 lbs although the range is actually between 5.8 and 6.8. Aviation uses 100 octanes of low lead fuel and they use 6 lbs to calculate weight and balance for aircraft.

I expect you mean Gasoline (petrol) which is a bit lighter than water. A gallon of water weighs 10 lbs. Do you need to know more accurately?
I assume you are referring to gasoline which has a specific gravity of .739 (at 60F)[1]. Water weighs 8.34 pounds per US liquid gallon. So 1 gallon of gas weighs 6.16 pounds.

Unleaded American auto gasoline which includes 10 percent alcohol weighs 6.3 pounds per gallon. Aviation gasoline 100ll weighs 6 pounds per gallon.
It would depend on the type and pressure of the gallon of gas - the higher the pressure, the more it would weigh.
According to the Science and Technology Desk Reference, a U.S. gallon of Gas weighs 6.1 pounds and an Imperial Gallon weighs 7.2 pounds.
