A gallon of diesel weighs approximately 7.1 pounds.
A gallon of diesel fuel weighs about 7.1 pounds (3.22 kg) at room temperature. This weight can vary slightly based on temperature and diesel grade, with No. 2 diesel being the most common type. Diesel is denser than gasoline, which weighs about 6.3 pounds per gallon.
Factors affecting diesel weight
- Temperature: Diesel expands when warm, slightly reducing density
- Diesel grade: No. 1 diesel is lighter than No. 2 diesel
- Altitude: Higher altitudes can affect fuel density
