How many barrels of oil does a super tanker hold?

A supertanker can hold between 200,000 to over 400,000 deadweight tons of oil, which translates to approximately 1.5 million to 3 million barrels of oil, depending on the specific design and capacity of the vessel. The exact capacity may vary among different supertankers, but they are among the largest ships used for transporting oil across oceans.
