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.
Teaspoon (Metric) (tsp (m))
The metric teaspoon is universally fixed at 5 mL, offering complete consistency across countries that use metric culinary measurements. This simplicity is a major advantage over historical teaspoon variations. In metric recipe writing—especially in Australia, New Zealand, and parts of Europe—teaspoons serve as standardized micro-measures that are easy to convert and scale. Its widespread adoption demonstrates the advantages of aligning traditional kitchen practices with the predictable structure of the metric system.
