About Gallons
A US gallon (gal) = 4 quarts = 128 fl oz ≈ 3.785 L. Gasoline, milk, water, paint, and pesticides are sold by the gallon in the US. About 20% smaller than the UK imperial gallon (4.546 L) - a critical difference when comparing fuel economy across the Atlantic. 1 US gal = 3.785 L = 4 qt = 128 fl oz.
About Milliliters
A milliliter (mL) is one thousandth of a liter (0.001 L) and exactly equal to one cubic centimeter (cc/cm³). It is one of the most commonly used units in everyday life - standard medicine doses, cooking measurements, and beverage labels all reference milliliters. A standard teaspoon holds about 5 mL, a tablespoon 15 mL, and a standard wine glass typically 150-250 mL. The milliliter is the workhorse of liquid measurement in medicine, cooking, chemistry, and consumer products worldwide, bridging the gap between the full liter and laboratory-scale measurements.
