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 Cubic Feet
A cubic foot (ft³) is the volume of a cube with sides of one foot (30.48 cm), equal to approximately 28.317 liters. It is widely used in US construction, HVAC engineering, natural gas distribution, and real estate. Natural gas consumption is billed in cubic feet (Ccf = 100 ft³, Mcf = 1,000 ft³); refrigerator, oven, and storage compartment capacity are rated in cubic feet; and concrete or soil orders are quoted in cubic yards or cubic feet. One cubic foot of water weighs approximately 62.4 pounds. Air conditioning units are sized in BTU per hour for room volumes measured in cubic feet.
