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 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).
