History of the 42-Gallon Oil Barrel
When filled with oil instead of fish or other commodities, a 42-gallon “tierce” weighed 300 pounds. The 42-gallon oil barrel was officially adopted in 1866. Today, a barrel’s refined products include about 20 gallons of gasoline, 12 gallons of diesel and 4 gallons of jet fuel and other products like liquefied petroleum gases and asphalt.
In August 1866 a handful of America’s earliest independent oil producers met in Titusville, Pennsylvania, and agreed that henceforth, 42 gallons would constitute a barrel of oil. Pennsylvania led the world in oil production as demand for kerosene soared.
