About these units
Cubic Centimeter (cm³)
A cubic centimeter equals 1 mL, representing the volume of a cube 1 cm per side. This dual identity makes it fundamental in medicine, laboratory science, and engineering. In medicine, cm³ is used when describing organ sizes, tumor volumes, or syringe capacities. In mechanics, engine displacements (e.g., "1500 cc") use cubic centimeters instead of liters, even though 1000 cm³ = 1 liter. The cm³ bridges small-scale measurements with scientific precision, making it indispensable across biology, chemistry, and automotive engineering.
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.
