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.
About Tablespoon (tbsp)
A US culinary unit of volume equal to exactly 1/16 of a US cup, or exactly 3 US teaspoons (≈ 14.7868 mL per NIST SP 811). Tablespoons are the standard US small-quantity cooking-measurement unit: butter portioning (1 stick = 8 tbsp), olive oil and cooking oil drizzles, salt and pepper to taste, fresh herbs, salad dressings, vinaigrettes, marinades, sauce reductions, and pharmaceutical dosing on US-labelled OTC liquid medications. US nutrition facts panels frequently use 'per 1 tbsp' as a serving size (peanut butter, mayonnaise, maple syrup, honey, jam). **Important**: the Australian tablespoon is 20 mL (not 15 mL) per AS 1014, set by the National Measurement Act — a 33% difference from the US tablespoon. The UK tablespoon (per BS 2050) and Canadian tablespoon are 15 mL — same as US. Recipes from Australia / NZ measuring by tablespoon should be flagged so international cooks can adjust. 1 tbsp (US) = 0.5 fl oz = 3 tsp = 14.79 mL.
