When transporting tons of rudely oil, it’s useful to be able to calculate the weight of her cargo come comply v weight regulations. Due to the fact that a gallon is a measure of volume and not weight, just how much does a gallon of rudely oil weigh?

How lot does a gallon that oil weigh? The load of crude oil ranges from 6.5 lbs/US gal come 8.5 lbs/US gal together crude oil varieties in class from light to heavy. Because the load of the oil is also impacted by transforms in temperature, the petroleum industry uses measurements that account for those changes.

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

Modern supertankers, choose the very large crude transport (VLCC) class, are able to host an estimated 84 million gallons or 2 million barrels of crude oil oil for every 318,000 metric tons. Ultra-large rudely carriers, or ULCCs, which weigh up to 550,000 deadweight tons, can lug up to 4 million barrels (source).

Barrels and Drums every Metric Ton

In comparison to the American stock Exchange, which actions oil in barrels, the European share Exchange reports the volume of oil in metric tons. If you understand the API gravity of the oil carried, you can calculate the stormy amount of barrels every metric ton. Friend simply add 131.5 come the API gravity and divide through the product of 141.5 and 0.159.

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

For hefty crude oil through an API selection of 25 API to 10, we get 6.96 barrels per metric ton to 6.29 barrels every metric ton or 5.31 come 4.80 drums.

Final Thoughts

As you can see, the load of a gallon that oil is straight 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 greater its worth is. Lighter oils produce higher levels the gasoline, diesel, and jet fuel, which is why castle command such a high price.

While the threshold standards in between light, medium, and also heavy crude vary widely, established by the Louisiana DNR is among the most generally cited. Top top average, a gallon the extra light crude will weigh 6.65 lbs/US gal, irradiate crude 7.03 lbs/US gal, medium crude 7.398 lbs/US gal, heavy crude 8 lbs/US gal, and also extra heavy crude will certainly weigh around 8.5 lbs/US gal.
