About Fluid Ounce (fl oz)
A US customary unit of liquid volume equal to exactly 1/128 of a US gallon (≈ 29.5735 mL). Fluid ounces are the universal US small-liquid-volume retail unit: beverage containers (a standard US Coke can is 12 fl oz, a Starbucks Grande is 16 fl oz, Trenta 30 fl oz), shampoo / lotion / personal-care bottles, US cocktail and bartending recipes (1.5 fl oz is the standard 'jigger' shot), wine pours (a standard restaurant pour is 5 fl oz; a generous home pour 6 fl oz), and home-cooking liquid measurements. **Important**: the US fluid ounce (29.5735 mL) is NOT the same as the UK Imperial fluid ounce (28.4131 mL) — the ~4% difference is usually inconsequential at consumer level but matters when scaling industrial formulations. The US fluid ounce is also distinct from the avoirdupois ounce (a weight unit ≈ 28.35 g), although for plain water the numerical values happen to coincide closely (1 US fl oz of water ≈ 1.04 oz mass).
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.

Understanding Quarts
The Quart (symbol: qt) is a unit of volume. 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.
It belongs to the imperial measurement system.
Quarts are commonly used in cooking, chemistry, fluid mechanics, and everyday liquid measurement.
