How Much Does Diesel Fuel Weigh Per Pound?

Fuel is the lubricant that keeps trucks on the road. If you want to haul profitable goods and keep your trucking firm afloat, you’ll need diesel fuel to get from point A to point B.

Although it’s a simple calculation, have you ever considered the intricacies of diesel fuel? Have you considered how much diesel fuel weighs? What’s the weight of a full tank of diesel fuel? Is there a difference in the weight of diesel based on the outside temperature? How does the weight of diesel fuel affect the weight of your truck, especially when it’s time to weigh it?

What is the weight of diesel fuel?

A gallon of diesel is approximately 7 pounds in weight. In the United States, diesel weighs somewhat less than 7 pounds per gallon (and slightly more than 7 pounds per gallon in Canada), but we’ll use 7 pounds per gallon to keep things simple.

What is the fuel weight of a full tank?

Semi-truck fuel tanks are available in a variety of sizes, but they typically store 125 to 300 gallons of petroleum. Each side of the tractor has a gasoline tank, with fuel apportioned between the two tanks to balance the truck’s total weight. Because diesel fuel weighs around 7 pounds per gallon, a full tank of diesel might weigh anywhere between 875 and 2,100 pounds.

Does the weight of diesel fuel change when it’s colder vs. warmer?

Yes, but it’s a teeny-tiny fraction of a percent. Take a look at this handy calculator. Let’s say the temperature is 16 degrees Fahrenheit and a gallon of diesel weighs 7.1 pounds. When the temperature is 106 degrees Fahrenheit, a gallon of diesel fuel weighs 6.8 pounds. Now set the temperature to 69 degrees Fahrenheit, which is a very pleasant temperature. The weight of a gallon of diesel fuel is 6.9 pounds. See? All of the differences are minor. Consider the following scenario: Depending on the size of the fuel tank, the temperature weight differential of diesel fuel will never be more than 10-50 pounds.

What does 100 gallons of diesel weigh?

To make things easy, we like to round off the weight of diesel fuel. When estimating the weight, use the round value of 7 lb. per gallon…. The weight of a hundred gallons is 700 lbs.

It weighs slightly more than 7 lb. per gallon in Canada, due to the larger gallon, and slightly less than 7 lb. per gallon in the United States, but it’s a good round number to work with when performing some’mental math.’

How much is a pound of diesel fuel weigh?

This should be a simple question to answer. It should have a straightforward response. But it’s not that straightforward, and every truck driver should be aware of it. How much weight will I gain if I fill my fuel tanks? We’ll start with the most direct answer in this post. Then we’ll talk about why you might be better off not filling those tanks.

Diesel fuel weights 6.91 pounds per gallon at 76 degrees Fahrenheit. That’s under typical atmospheric conditions. To make things easy, most truckers round this up to 7 pounds per gallon. A Canadian gallon is slightly larger than an American gallon, measuring 4.5 litres vs 3.8 litres. A gallon of Canadian (imperial) water weighs 8.4 pounds. For the purposes of this discussion, we’ll use the US gallon.

How heavy is a gallon of fuel?

A gallon of conventional fuel (such as gasoline) weighs six pounds, according to the Science and Technology Desk Reference. Water, on the other hand, weighs around 8.4 pounds per gallon.

Which is heavier a gallon of milk or water?

A gallon is a unit of volume, and the mass of a constant volume is directly proportional to its density. Milk is around 87 percent water, with the exception of fat, containing other compounds that are heavier than water. A gallon of milk weighs significantly more than a gallon of water.

Are gravity fed fuel tanks legal?

Here are some of the laws (regulations) that apply to gravity feed fuel tanks, as well as why they are prohibited.

  • 7.4.5; Fuel withdrawal fittings, 49 CFR CH.III (393.67) When a tank is full, the fittings that allow gasoline to be removed from it must be situated above the noraml level of fuel in the tank.
  • To put it another way, the fuel must come from the top of the tank, not from a bottom-mounted fitting. ATTA’s aluminum tanks will not have any fittings on the bottom for safety concerns. Look at your OEM tank if you’re unsure.

How do you calculate the weight of diesel fuel?

Water has a density/specific gravity of 1.0 (SG=1.0) because it weighs about 1kg per litre (1000L = 1000Kg).

Remember that 1 litre of water weighs 1 kilogram, so 1920 litres of water weigh 1920 kilograms; however, if the tank is filled with a different fluid, you must consider the following factor, which affects the weight of the tank when full.

Diesel fuel, for example, has a specific gravity (SG) of 0.82, making it lighter than water (SG =1.0). To calculate the weight of diesel in the same sized storage tank, multiply the volume (litres) by the specific gravity (SG).

To summarize, a 45kg diesel tank with a volume of 1920 litres weighs:
