About these units
Barrel (Oil) (bbl (oil))
An oil barrel is defined as 42 US gallons, or 158.987 liters, and is a fundamental unit in the petroleum industry. This peculiar size traces back to the early Pennsylvania oil fields, where producers standardized whiskey barrels and modified wooden casks for oil transport. The need for consistent trade volumes cemented the 42-gallon barrel as the industry norm. Today, global oil production, pricing, and consumption are expressed in barrels—from daily OPEC reports to energy market forecasts. Even though oil is no longer physically shipped in barrels, the unit remains deeply embedded in international energy economics.
Hundred-Cubic Foot (100 ft³)
This is simply another expression of 100 cubic feet, used in billing systems, engineering calculations, and pipeline monitoring. Where the abbreviation CCF is standard for water utilities, many technical publications explicitly use "100 ft³" to avoid ambiguity. Engineers working on ventilation systems, gas pipelines, or storage capacities may choose this form for clarity in calculations. Its simplicity and direct reference to cubic feet make it a universally understood expression in industries that rely on imperial volume measurement.
