About Quart (qt)
A US customary unit of volume equal to exactly 2 US pints, 4 US cups, or 1/4 of a US gallon (≈ 946.353 mL). Quarts are a common US retail size for milk and juice cartons (the classic 'quart of milk' US carton), motor oil and other automotive fluids (1 quart bottles are the de-facto US automotive-fluid retail SKU — engine oil, transmission fluid, brake fluid, power steering, coolant), interior paint (consumer paint sample cans are 1 qt; many specialty / craft paints are quart-only), Crock-Pot / slow-cooker capacity ratings (2 qt, 4 qt, 6 qt, 8 qt), and home-canning / preserving (Ball Mason wide-mouth quart jars). A US quart is conveniently almost exactly one litre (~5.4% less), so many internationally-traded products use a single-SKU 1-litre size that satisfies both US quart-equivalent customers and metric markets. **Important**: the UK Imperial quart is 1.1365 L — 20% larger than the US quart. 1 US qt = 32 fl oz = 0.9464 L = 0.8327 UK qt.
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.
