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 Cup (cup)
A US customary unit of volume equal to exactly 8 US fluid ounces or ≈ 236.588 mL. Cups are the dominant measurement unit in American home cooking and published US recipes per the USDA Recipe Standardization guidelines and most major US recipe-publishers (Food Network, NYT Cooking, Bon Appétit, Joy of Cooking): a standard US measuring cup set includes 1, 1/2, 1/3, and 1/4 cup nesting scoops. Outside North America, recipes typically use grams (solids) and millilitres (liquids), making cup → mL one of the most-needed kitchen conversions for international cooks working from American cookbooks. **Important**: cup sizes are NOT internationally uniform — the US cup is 236.6 mL, the Imperial cup (UK) is 284 mL but rarely used in modern UK recipes, the metric cup (Australia, NZ) is 250 mL, and the Japanese cup (gō, 合) is 180 mL. A recipe saying '1 cup' without identifying its origin can lead to ±25% measurement errors, especially impactful in baking where ratios matter.
