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 Teaspoon (tsp)
A US culinary unit of volume equal to exactly 1/3 of a US tablespoon, or 1/48 of a US cup (≈ 4.92892 mL per NIST SP 811). Teaspoons are the smallest everyday US kitchen measurement: salt, pepper, ground spices, vanilla extract, almond extract, baking powder, baking soda, instant yeast, dry-mustard powder, and most powdered-spice quantities in published recipes. The pharmaceutical 'teaspoon' (used on OTC liquid-medication dosing labels and the AAP-recommended dosing-syringe scale) is rounded to exactly 5.00 mL for international consistency and dose-calculation simplicity — slightly larger than the kitchen teaspoon (4.93 mL) but the 1.4% difference is within label-precision tolerance. **Important**: same Australian-vs-rest-of-world distinction applies — Australian teaspoon is 5 mL per AS 1014, US/UK/Canadian teaspoon ≈ 4.93 mL. Recipes from Australia using tsp work out the same in practice. 1 tsp (US) = 1/3 tbsp ≈ 4.93 mL ≈ 1/6 fl oz.
