## What is the weight of 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.

## Does 1 litre weigh 1 kg?

Litres are most typically used for objects that are measured by the capacity or size of their container (such as fluids and solids that may be poured), whereas cubic metres (and derived units) are most commonly used for items that are measured by their dimensions or displacements. The litre is also commonly used in some computed metrics, like as density (kg/L), to facilitate comparisons with water density.

When measured at its maximum density, which occurs at around 4 °C, one litre of water weighs almost exactly one kilogram. As a result, 1000th of a litre of water, also known as one millilitre (1 mL), has a mass of around 1 g, while 1000 litres of water has a mass of about 1000 kg (1 tonne or megagram). This relationship holds because the gram was initially defined as the mass of 1 mL of water; however, because the density of water changes with temperature and, very slightly, with pressure, this definition was abandoned in 1799.

The density of water is now recognized to be influenced by the isotopic ratios of oxygen and hydrogen atoms in a given sample. The density of Vienna Standard Mean Ocean Water, which is pure distilled water with an isotopic composition indicative of the average of the world’s oceans, has been determined by modern measurements.

## 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:

#### National and Regional

Highest At 146.8 pence per litre, the South East has the highest unleaded pricing.

Northern Ireland has the lowest unleaded price, at 142.7 pence per litre.

The South East has the highest diesel price, at 150.3 pence per litre.

The average price of unleaded in supermarkets is now 143.0 pence per litre. The price difference between supermarket pricing and the UK average for unleaded gasoline has widened to 2.7 pence per litre.

## Does diesel weigh more than gas?

We’ve also witnessed the opposite: one of our clients put gasoline directly into one of his tractor’s diesel fuel tanks by accident. He wanted to know whether there would be any issues.

If you work in the fuel industry long enough, you’ll come across a situation like this at some point. Mixing gasoline with diesel is never a good idea, but it isn’t always a disaster. The most important factor is how much of each you unintentionally added. If that happens to you, here’s what you may expect.

### Big Differences between gasoline and diesel fuel

When we talk about diesel fuel, we’re talking about #2 diesel fuel, whether it’s for on-road or off-road use.

When attempting to foresee what problems might occur if one fuel is mistakenly mixed with the other, you must consider the most significant distinctions between the two fuels.

Because diesel fuel is made up of big molecules, it is heavier than gasoline. Because of the difference in density and viscosity, it atomizes differently. It also has a much greater flash point and autoignition temperature. And, given these, the inverse can be applied as well. Gasoline is lighter than diesel and flashes at a lower temperature.

When you bring in fuel that isn’t supposed to be there, these variations in physical qualities cause difficulties in engines and fuel systems.
