Gasoline Weight Calculator: How Much Gas Weights? (Gallons -> Lbs)

When you are putting gas into a car, how much weight are you adding? We only know how many gallons of gasoline (volume) we put into the can; the gas station does tell us how many pounds of weight that is. To calculate that, we need to apply the 5.97-6.51 lb/gallon density (at 59°F or 15°C temperature).

To help you figure out how much gasoline weights, we prepared 2 useful tools you can freely use, namely:

1. Gasoline Weight Calculator. Here, you just insert how many gallons of gasoline you used, and you get the weight of that gasoline in pounds (lbs) immediately.
2. Gasoline Weight Chart. We calculated the weight of 0.1-100 gallons of gasoline, and summarized all the results in a neat gasoline weight chart.

Quick Example: Let’s say you put 10 gallons of gasoline in your tank. The average standard density of gasoline is 6.30 lb/gallon. How much does 10 gallons of gasoline weigh? We just multiply 10 gallons × 6.30 lb/gallon = 63 lbs. Now we know that 10 gallons of gasoline weighs about 63 lbs.

This is just one example. With the calculator, you can insert any number of gallons, and you will get the weight of that gasoline. Further on, you can also consult the gasoline weight chart. Here is the gasoline weight calculator:

Here is how this calculator works:

Let’s say you filled a full tank; it was 11.37 gallons of gas. How much does that gasoline weigh? You simply insert ‘11.37‘ in the gasoline gallons input field, and get this result immediately (screenshot):

We immediately see that 11.37 gallons of gasoline weighs 71.63 lbs. We created a similar diesel fuel weight calculator here; you can freely use it.

Let’s have a look at the weight chart:
