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.
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.
