How many US gallons are in one oil barrel?

• A. 32
• B. 42
• C. 50
• D. 55

Answer: (B)

In the oil industry, the volume used for crude oil and most petroleum products is defined by a fixed-sized barrel. In the United States, one barrel equals 42 US gallons. This convention dates back to the 19th century and remains the standard for trading and reporting oil volumes, providing a consistent basis for pricing and measurements. 42 gallons is also about 158.99 liters or roughly 5.614 cubic feet. Other numbers aren’t the standard barrel size in US oil trading, so 42 gallons is the correct amount.
