Gallon (US)
The US gallon, symbol gal, equals 4 quarts, 8 pints, or 128 fluid ounces (~3.785 liters). Its origins trace to English wine and ale measures but were standardized in the US in the 19th century. Gallons are used for beverages, fuel, and large-volume recipes. While metric liters are the dominant unit of measurement in most countries, gallons remain widely used in the United States for everyday and industrial liquid measurements.
Pint (US)
The US pint is a customary unit equal to 2 cups or 16 fluid ounces (~473.176 milliliters). Derived from British measures, it has been standardized in the US for liquid volumes. Pints are commonly used for beverages, dairy products, and liquid ingredients. Its use simplifies larger-volume measurements in recipes while maintaining compatibility with smaller units, such as cups and fluid ounces.
