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 Milliliter (mL)

A metric unit of volume equal to exactly one thousandth of a litre (0.001 L) and exactly one cubic centimeter (1 mL ≡ 1 cm³ per BIPM). The mL is the universal small-volume unit in clinical medicine and pharmacy (USP / EP / JP / BP / IP pharmacopoeial dosing per ISO 13485 medical-device standards), laboratory chemistry (titration burettes, analytical glassware per ASTM E542), small-batch cooking outside the US, perfume and personal-care products (EU Cosmetic Regulation requires labelling in mL), and beverage packaging (a 500 mL water bottle, 750 mL wine, 700 mL standard spirits bottle in most of the world / 750 mL in US). Reference values: a typical Luer-lock medical syringe 1-60 mL, US shot glass ~44 mL (1.5 fl oz), standard saline IV bag 250-1,000 mL, espresso shot ~30 mL, retail vape juice 30/60/120 mL. In medical and laboratory contexts, mL and cc (cubic centimeters) are used interchangeably — both equal one cm³.
