Find how much gasoline or diesel weighs: enter gallons or liters to get the weight in pounds and kilograms using a typical fuel density, or your own.

Density varies with blend and temperature, so preset results are estimates.

Gasoline Weight Formula

The following two example problems outline the steps and information needed to calculate the Gasoline Weight.

GW = GV ร— D

Variables:

  • GW is the Gasoline Weight (lbs)
  • GV is the gasoline volume (US gallons); D is the density (lb/US gal)

To estimate gasoline weight, multiply the volume in US gallons by density in lb/US gal. The calculator defaults to 6.30 lb/US gal; choose the Census conversion or a custom measured density when appropriate. Density depends on blend and temperature.

How to Calculate Gasoline Weight?

The following steps outline how to calculate the Gasoline Weight.


  1. First, determine the gasoline volume (gallons). 
  2. Next, choose a density basis and use GW = GV ร— D.
  3. Finally, calculate the Gasoline Weight.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

gasoline volume (gallons) = 15

GW = 15 ร— 6.30 = 94.5 lb using the default estimate.
