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.
Kiloliter (kL)
A kiloliter equals 1,000 liters, identical to 1 cubic meter, and is used in water management, municipal planning, agriculture, and commercial storage. Utility companies measure household water usage in kiloliters. Irrigation requirements, swimming pool volumes, and cistern capacities are also commonly expressed in this unit. Its equivalence to the cubic meter gives it flexibility—metric engineers may prefer m³, while public-facing documentation may use kL for clarity.
