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.
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.
