Gasoline Weight Calculator

Reviewed By: Patrick Myers (BSME)

Enter the gasoline volume (gallons) into the Gasoline Weight Calculator. The calculator will evaluate the Gasoline Weight.

Volume / Weight / Density

Fuel Load & Payload

Enter any 2 values (Volume, Weight, Density) to calculate the missing one.

Fuel Type (presets @ 60°F) Volume

Weight

Density

Apply temperature compensation (adjust density from 60°F / 15.6°C)

Uses a typical gasoline volumetric expansion of 0.00095 per °C.

Gasoline Weight Formula

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

GW = GV * 6.073

Variables:

GW is the Gasoline Weight (lbs)
GV is the gasoline volume (gallons)

To calculate the gasoline weight, multiply the volume of gasoline in gallons by 6.073.

How to Calculate Gasoline Weight?

The following steps outline how to calculate the Gasoline Weight.

First, determine the gasoline volume (gallons).
Next, gather the formula from above = GW = GV * 6.073.
Finally, calculate the Gasoline Weight.
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 = GV * 6.073 = ?

Follow-Up Calculations

A 20-gallon tank of gasoline weighs about 120 to 125 pounds, so a full fill-up can noticeably shift the car’s balance if the tank sits behind the rear axle. Use the axle balance calculation to see how much that extra fuel changes front-to-rear loading; even a small percentage shift can affect handling, tire wear, and suspension sag.

Hauling ten 5-gallon fuel cans means moving roughly 300 pounds of gasoline before you count the cans themselves, straps, or a spill tray. The trailer payload limit helps you check whether your trailer still has room for everything else, which is important because cargo ratings include the container weight too.

If a full 15-gallon tank adds about 90 pounds to a compact car, the brakes have to generate a little more clamping force every time you stop hard. The required brake clamp force shows how much hydraulic pressure and pad force are needed for a heavier vehicle, so you can compare a half tank versus a full tank in the same stopping scenario.
