When transporting tons of crude oil, it’s useful to have the ability to calculate the weight of your cargo come comply through weight regulations. Because a gallon is a measure of volume and not weight, just how much walk a gallon of crude oil oil weigh?

How much does a gallon the oil weigh? The weight of crude oil oil ranges from 6.5 lbs/US gal come 8.5 lbs/US gal together crude oil varieties in grade from irradiate to heavy. Due to the fact that the weight of the oil is also impacted by changes in temperature, the petroleum market uses dimensions that account because that those changes.

A supertanker has actually a deadweight capacity of end 75,000 tons. The an initial of the supertankers, the SS world Leader, was built in 1956. She had actually 52 tanks in all and also could host over 1,300,000 gallons full (source).

Modern supertankers, choose the very huge crude transport (VLCC) class, are able to host an estimated 84 million gallons or 2 million barrels of crude oil because that every 318,000 metric tons. Ultra-large crude oil carriers, or ULCCs, i beg your pardon weigh up to 550,000 deadweight tons, can bring up come 4 million barrels (source).

Barrels and Drums every Metric Ton

In contrast to the American share Exchange, which measures oil in barrels, the European share Exchange reports the volume of oil in metric tons. If you know the API heaviness of the oil carried, you have the right to calculate the unstable amount of barrels per metric ton. Girlfriend simply add 131.5 come the API gravity and also divide by the product the 141.5 and 0.159.

Going ago to our benchmarks, we get 7.6 barrels every metric ton because that West Texas Intermediate, 7.54 barrels for Brent Crude, and also 7.22 barrels because that Dubai Crude. Using 55-gallons drums, we get 5.8, 5.76, and also 5.5 for every metric ton, respectively.

For heavy crude oil v an API range of 25 API come 10, we get 6.96 barrels every metric ton come 6.29 barrels every metric ton or 5.31 come 4.80 drums.

Final Thoughts

As you can see, the weight of a gallon the oil is directly dependant top top its grade as measured through the oil’s API gravity. The greater the oil’s API gravity, the lighter the oil is, and the greater its worth is. Lighter oils produce greater levels of gasoline, diesel, and also jet fuel, which is why they command such a high price.
