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 Pecks

A peck (pk) is a dry volume unit in the US customary system equal to 2 dry gallons or 8 dry quarts - approximately 8.810 liters. It was historically used to measure grain, produce, and bulk goods at market - a 'peck of potatoes' or 'peck of apples' was a standard quantity. The nursery rhyme 'Peter Piper picked a peck of pickled peppers' has made the peck culturally familiar even though it is rarely used in modern commerce. Four pecks equal one US bushel. In agriculture, pecks still appear in older US crop yield tables, traditional market records, and historical American cookbooks.
