About these units
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.
Gallon (US) (gal (US))
The US gallon is defined as exactly 231 cubic inches, or 3.785411784 liters. It is widely used in American commerce for gasoline, milk, water, and other household liquids. Its historical roots lie in old English wine and ale gallons, whose varying definitions ultimately led to divergent US and UK systems. Today, the US gallon remains deeply embedded in American culture, especially in automotive contexts—fuel economy ratings such as "miles per gallon" (MPG) illustrate its everyday relevance. Despite the global shift toward metric volume units, the US gallon persists due to familiarity and regulatory inertia. It remains an iconic unit, symbolizing uniquely American measurement traditions.
