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.
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).
