About Oil Barrels
An oil barrel (bbl) = exactly 42 US gallons ≈ 158.99 L - established by the Pennsylvania oil industry in the 1860s and now the global petroleum standard. Global oil production, OPEC quotas, and crude spot prices are all quoted in barrels or Mb/d (millions of barrels per day); world consumption ~100 Mb/d in 2024. 'Bbl' derives from the 'blue barrel' mark on petroleum containers. 1 bbl = 42 US gal ≈ 159 L.
About Quarts
A quart (qt) is a US customary volume unit equal to 2 pints or 4 cups - approximately 946.353 mL (just under one liter). Motor oil, paint, and large containers of juice or milk are commonly sold by the quart in the United States. The term 'quart' derives from the Latin 'quartus' (fourth), as it is one quarter of a gallon. The US liquid quart (946 mL) differs from the UK imperial quart (1136 mL). Engine coolant, transmission fluid, and many automotive products are measured and sold in quart containers in the US. Four quarts equal one US gallon.
