About Cup (cup)
A US customary unit of volume equal to exactly 8 US fluid ounces or ≈ 236.588 mL. Cups are the dominant measurement unit in American home cooking and published US recipes per the USDA Recipe Standardization guidelines and most major US recipe-publishers (Food Network, NYT Cooking, Bon Appétit, Joy of Cooking): a standard US measuring cup set includes 1, 1/2, 1/3, and 1/4 cup nesting scoops. Outside North America, recipes typically use grams (solids) and millilitres (liquids), making cup → mL one of the most-needed kitchen conversions for international cooks working from American cookbooks. **Important**: cup sizes are NOT internationally uniform — the US cup is 236.6 mL, the Imperial cup (UK) is 284 mL but rarely used in modern UK recipes, the metric cup (Australia, NZ) is 250 mL, and the Japanese cup (gō, 合) is 180 mL. A recipe saying '1 cup' without identifying its origin can lead to ±25% measurement errors, especially impactful in baking where ratios matter.
About Gallon (US) (gal)
A US customary unit of liquid volume equal to exactly 3.785411784 litres (231 cubic inches by the 1707 Queen Anne wine-gallon definition), or exactly 128 US fluid ounces. The US gallon is the dominant US retail and industrial liquid-volume unit: gasoline pricing and fuel economy (the US EPA window-sticker MPG figures use US gal), milk and beverage retail containers, residential and commercial water heaters (40 / 50 / 75 / 80 gal sizes), swimming-pool and aquarium capacity ratings, US paint and coatings cans, household oil-heat tank sizing, and US-domestic-shipping bulk-liquid descriptors. **Important**: the US gallon ≠ the UK Imperial gallon (4.54609 L = 1.20095 US gal) — a recurring source of confusion in trans-Atlantic fuel-economy comparisons (40 UK mpg = 33.3 US mpg despite identical real efficiency). One US gal of water at 60 °F weighs 8.345 lb. Convert US gal to L by multiplying by 3.7854; to mL by 3,785.4; to fl oz by 128.
