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.
Microliter (µL)
A microliter is 10⁻⁶ liters, a standard unit in laboratories worldwide. It is indispensable in pipetting, sample preparation, PCR reactions, enzyme tests, and pharmaceutical formulation. Most laboratory pipettes are designed with microliter precision, and many experiments rely heavily on the ability to dose volumes like 10 µL or 100 µL with high accuracy. Its use outside laboratories includes medical diagnostics, such as blood sampling, allergy testing, and microdose vaccine research. The microliter is an essential unit linking biological processes to controlled experimental conditions.
