About these units
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.
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.
