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 Liter (L)
A metric unit of volume equal to exactly 0.001 cubic meters (one cubic decimeter), defined by the BIPM since 1964. The litre is accepted for use with the SI per the BIPM SI Brochure and is the global standard for beverages and beverage labelling under the EU Food Information to Consumers Regulation 1169/2011 and Codex Alimentarius, fuel economy (km/L outside North America), automotive engine displacement (e.g., '3.0 L turbo'), medical fluid volumes (TPN bags, IV fluids, blood volume), industrial chemical-process material balances (Aspen HYSYS / CHEMCAD default volumetric unit alongside m³), and HVAC/plumbing flow specs. Reference values: a standard wine bottle is 0.75 L, a Coke can 0.33 L, a US half-gallon ~1.89 L, a midsize-car fuel tank 50-70 L, a household water heater 150-300 L, a standard IBC industrial-chemical tote 1,000 L. One litre of pure water at 4 °C and 1 atm weighs almost exactly 1 kg — a deliberate design feature of the original metric system. 1 L = 1,000 mL = 1,000 cm³ = 1 dm³ = 0.2642 US gal = 33.81 US fl oz.
