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 Miles

A cubic mile (mi³) ≈ 4.168 km³ = 4.168 × 10¹² L. Lake Superior: ~2,900 mi³ (world's largest freshwater lake by surface area). Total volume of all glaciers and ice caps (excl. Antarctica and Greenland): ~170,000 mi³. Volcanic magma chamber sizes and major US aquifer volumes are sometimes quoted in cubic miles in American geoscience literature. 1 mi³ ≈ 4.168 km³.
