How much does a gallon of gasoline weigh? How a lot does a gallon of diesel weigh? These inquiries are vital as soon as you’re trying to decide what you have to use for your auto, devices, and devices, or for your emergency power supply. And yes, we’ll be assuming that you’re interested in the weight of gasoline and not simply any type of gas (e.g. oxygen).

So, the answer below is, of course, relative, as weight is contingent on various other factors. But, to offer you an average number, a UNITED STATE gallon of gasoline weighs around 6 pounds according to the Science and also Technology Workdesk Reference. For compariboy, a U.S. gallon of water weighs around 8.4 pounds.


To offer you a clearer idea of how much does gas weigh and why, yet, let’s go over the standard formula together.

The top quality requirement of gasoline, as stated by ASTM D4052 (The Standard test method for density, loved one density, and also API gravity of liquids by Digital Density Meter), is suggested to be between 0.71 and 0.78 g/cm3 in a traditional thickness measurement of 15°C (59°F).

So, if we usage that 1 gallon equates to 4 qts; 1 liter equates to 1.1 qt, and 1000 ml equal 1 liter with a density of 0.78 g/mL (the maximum) we’ll come up to 2836 grams. And because 454g = 1 lb, this offers us a weight of 6.2 UNITED STATE pounds for a gallon of gasoline. If we were to gain an extra average density than 0.78 g/mL we would’ve gained precisely 6 pounds.

Anvarious other method to calculate it is by going with the Imperial gallon figure and converting it to UNITED STATE gallons. So, if 1 Imperial gallon of water weight 10 pounds and we take a gasoline density of 0.73 g/mL this time, this suggests that one Imperial gallon of gasoline weighs 7.3 pounds. And given that 1 U.S. gallon is equal to 0.83 Imperial gallons, we deserve to ssuggest multiply 7.3 by 0.83 and also we’ll get the weight of a gallon of gasoline to be 6.059 pounds.


We have the right to also look at the metric worths. To execute this we’ll have to begin through the truth that 1 liter of water weighs 1 kilogram. If we aspect in a particular gravity of 0.72 then if for UNITED STATE Gallons we’ll obtain 3.78 liters and for Imperial gallons, we’ll obtain 4.54 liters. This is a straightforward calculation to make bereason the base connection of the Imperial or Metric values is based upon water through a certain gravity of 1. So, it’s simple to recall it as 1 Kg a liter or 10 pounds a gallon.

As for diesel, it has actually a density of roughly 0.832 g/cm^3 or 0.834 kg/LGallon of diesel deserve to be calculated to have a mass of 6.943 pounds per gallon which is a bit heavier than gasoline.

. So, a UNITED STATE For the Imperial system, the number is 8.338 pounds per Imperial gallon.
