What You'll Learn
The weight varies with temperature
The weight of diesel fuel depends on various factors, including the type of diesel, measurement units, and temperature. The most common standard for diesel fuel in the United States is ASTM D975, while the European Union and many other countries follow the EN 590 standard.
The three main types of diesel fuel are:
- Number 1 (1-D): Used in cold weather due to its lower viscosity and similar chemical properties to kerosene. It weighs around 7.30 pounds per gallon.
- Number 2 (2-D): The most common type for normal and warm weather conditions due to its higher viscosity. It typically weighs between 6.96 and 7.09 pounds per gallon at room temperature.
- Number 4 (4-D): Used for stationary units and low to medium-speed engines. It has a greater density and weighs around 8 pounds per gallon.
Now, let's focus on how the weight of diesel fuel varies with temperature:
The temperature has a significant impact on the weight of diesel fuel. At colder temperatures, diesel fuel becomes denser and weighs more. For example, at 32°F, a gallon of 2-D diesel can weigh around 7.05 pounds. As the temperature drops further, the weight will slightly increase.
On the other hand, diesel fuel expands at higher temperatures, leading to a decrease in weight. When the temperature rises to 100°F or above, a gallon of 2-D diesel will weigh approximately 6.8 pounds. This weight variation is due to the change in density with temperature. The European Standards Organization (CEN) mandates that diesel fuel must fall within a specified density range.
It's worth noting that the weight difference due to temperature changes might seem minor for a single gallon, but it can add up quickly when dealing with large fuel tanks. For instance, a 100-gallon fuel tank can experience a weight difference of over a hundred pounds just from temperature fluctuations. Therefore, truck drivers and fuel handlers must consider the temperature-weight relationship when calculating the total weight of their vehicles or fuel inventories.

The weight of diesel fuel varies depending on the type of diesel, its temperature, and the units used for measurement.
Types of Diesel Fuel
Diesel fuel can be categorized into different types, each with its unique composition, cetane levels, and additives, as well as viscosities and pour points. The three main classes of diesel fuel are Number 1 (1-D), Number 2 (2-D), and Number 4 (4-D). Number 1 diesel, often considered a premium fuel due to its added lubricants and detergents, is primarily used in cold weather conditions as it has a lower viscosity. Number 2 diesel, the most common form for normal and warm weather, has a higher viscosity than Number 1. Number 4 diesel is thicker and intended for low-speed, off-road industrial equipment. Other types of diesel fuel include synthetic diesel and biodiesel.
Temperature
The temperature of the diesel fuel also affects its weight. For example, at 16 degrees Fahrenheit, one gallon of diesel fuel weighs 7.1 pounds, while at 106 degrees Fahrenheit, the same gallon weighs 6.8 pounds. At a comfortable temperature of 70 degrees Fahrenheit, the weight is 6.9 pounds.
Units of Measurement
The weight of diesel fuel can be measured in various units, such as pounds per gallon or pounds per cubic foot. Additionally, the use of different gallon measurements, such as Imperial gallons or US gallons, can lead to variations in the reported weight of diesel fuel. For instance, an Imperial gallon of diesel fuel with an average density of 51.84 pounds per cubic foot would weigh approximately 8.29 pounds, while a US gallon would be about 7.1 pounds.
In summary, the weight of one imperial gallon of diesel fuel can vary depending on the specific type of diesel, the temperature at which it is measured, and the units of measurement used. It is important to consider these factors when calculating the weight of diesel fuel to ensure accurate estimations.

The weight varies with region
The weight of diesel fuel varies with temperature, location, and unit of measurement.
In the US, diesel weighs about 7 pounds per gallon, though the weight varies with temperature. For example, at 16 degrees Fahrenheit, one gallon of diesel fuel weighs 7.1 pounds, while at 106 degrees Fahrenheit, the same gallon of diesel fuel weighs 6.8 pounds. In Canada, diesel weighs slightly more than 7 pounds per gallon. The discrepancy between the weight of diesel in the US and Canada is due to differences in fuel standards. Canada's fuel standards tend to favour the European EN 590 standard, which has a higher cetane number. Cetane number is a measure of the ignition quality of the fuel, with higher cetane numbers corresponding to fuels that ignite more readily.
The weight of diesel fuel also depends on the unit of measurement used. While diesel fuel is often measured in gallons, it can also be measured in litres. One litre of diesel weighs about 1.83 lbs. Additionally, there are differences between the US gallon and the Imperial gallon, with the US gallon being smaller. An Imperial gallon of diesel fuel with an average density of 51.84 lb/ft3 would weigh 8.29 lbs, while a US gallon of diesel fuel at the same density would weigh 7.09 lbs.
The climate across the US varies widely depending on location and time of year, which can affect the weight of diesel fuel. For example, in New England and the Mid-Atlantic States, a gallon of number 2 diesel fuel weighs between 6.96 lbs and 6.91 lbs within the room temperature range of 59°F to 76°F. At colder temperatures like 32°F, a gallon of diesel will weigh about 7.05 lbs.
In summary, the weight of diesel fuel varies depending on temperature, location, and unit of measurement. While diesel fuel generally weighs around 7 pounds per gallon in the US, there can be slight variations due to regional differences in fuel standards and climate.
