An oil barrel, also known as a petroleum barrel, is the standard unit of volume for crude oil and petroleum products in the oil industry. One barrel equals exactly 42 US gallons or approximately 159 liters. This measurement was standardized in the 1870s and became the global benchmark for oil trading. Despite advances in measurement technology, the barrel remains the primary unit for pricing and trading crude oil on international markets like NYMEX and ICE.
A US gallon is a unit of liquid volume commonly used in the United States for measuring fuel, beverages, and other liquids. One US gallon equals 231 cubic inches or approximately 3.785 liters. The gallon is divided into four quarts, eight pints, or 128 fluid ounces. It's important to note that the US gallon differs from the Imperial gallon used in the UK and other Commonwealth countries, which is approximately 20% larger.
