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

How much does a gallon of oil weigh? The weight of rudely oil varieties from 6.5 lbs/US gal to 8.5 lbs/US gal together crude oil ranges in grade from light to heavy. Because the load of the oil is also affected by alters in temperature, the petroleum sector uses dimensions that account because that those changes.

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

Modern supertankers, prefer the very large crude carrier (VLCC) class, space able to organize an estimated 84 million gallons or 2 million barrels of crude oil for every 318,000 metric tons. Ultra-large rudely carriers, or ULCCs, i beg your pardon weigh up to 550,000 deadweight tons, can carry up come 4 million barrels (source).

Barrels and Drums per Metric Ton

In comparison to the American stock Exchange, which actions oil in barrels, the European stock Exchange reports the volume that oil in metric tons. If you know the API gravity of the oil carried, you have the right to calculate the turbulent amount that barrels per metric ton. Girlfriend simply include 131.5 to the API gravity and also divide by the product that 141.5 and 0.159.

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

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

Final Thoughts

As you have the right to see, the weight of a gallon that oil is directly dependant on its grade as measured by the oil’s API gravity. The greater the oil’s API gravity, the lighter the oil is, and the higher its worth is. Lighter oils produce higher levels of gasoline, diesel, and also jet fuel, which is why castle command such a high price.

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