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

How much does a gallon of oil weigh? The weight of rudely oil arrays from 6.5 lbs/US gal to 8.5 lbs/US gal as crude oil varieties in class from light to heavy. Since the load of the oil is also impacted by changes in temperature, the petroleum sector uses measurements that account because that those changes.

A supertanker has actually a deadweight capacity of end 75,000 tons. The very first of the supertankers, the SS cosmos Leader, was constructed in 1956. She had 52 tanks in all and also could organize over 1,300,000 gallons complete (source).

Modern supertankers, choose the very large crude transport (VLCC) class, room able to host an approximated 84 million gallons or 2 million barrels of rudely oil because that every 318,000 metric tons. Ultra-large rudely carriers, or ULCCs, i m sorry weigh as much as 550,000 deadweight tons, can lug up to 4 million barrels (source).

Barrels and also Drums per Metric Ton

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

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

For hefty crude oil with an API variety of 25 API to 10, we obtain 6.96 barrels per metric ton come 6.29 barrels per metric ton or 5.31 to 4.80 drums.

Final Thoughts

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