The standard 42-gallon oil barrel was established in Pennsylvania during the early American oil industry in the 1860s. Prior to standardization, various barrel sizes were used. The 42-gallon standard was officially adopted by the U.S. geological survey and the U.S. Bureau of Mines in 1872. Today, while physical barrels are rarely used for oil transport, the unit remains the standard volume measure in the global petroleum industry.
