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.

## 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 heavy is 150 gallons diesel?

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 is the weight of 1 gallon of diesel?

Yes, but only a smidgeononononononononononononononononon (check out this calculator if you want to see how much). At 16°F, a gallon of diesel weighs 7.1 pounds; at 106°F, the same gallon weighs 6.8 pounds.

## How much does 1 gallon of #2 diesel weigh?

Now that you have a better understanding of weight station operations, you may go on to learning about the weight of diesel fuel.

Per gallon, diesel fuel weighs between 7.25 and 7.5 pounds. It’s a distillate fuel, which means it’s been cooked to eliminate any inedible components. You can detect a modest difference in weight due to changes in humidity or temperature outside, but it’s minor, and truckers aren’t concerned about such a minor difference.

It’s also worth noting that diesel doesn’t really evaporate. It does, however, dissipate into thin air. Some truckers may argue that this should be taken into account when weighing trucks, however vaporization has insufficient impact to cause a weight difference.

To aid mental math, diesel fuel should be calculated to a factor of seven. It will take longer if you want to do the exact weight, but you will know the exact weight of your fuel. Some people like to round up to the nearest eight to ensure that they never go above the limit.

## 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:

## 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.

## How many gallons does a diesel pickup truck hold?

When the radius of operation is taken into account, a semi truck tank typically holds 120 to 150 gallons of fuel, implying that two tanks can hold up to 300 gallons of fuel.
