About Tablespoons and Fluid ounces
Tablespoons (tbsp): Three teaspoons, or about 15 mL; the US legal tablespoon is exactly 14.7868 mL, although international cooking convention is 15 mL. Common uses: Mid-range cooking measurements (oil, vinegar, honey, peanut butter), baking (small quantities of cocoa powder, cornstarch, baking soda).
Fluid ounces (fl oz): 1/128 of a US gallon, or 29.5735 mL; the UK imperial fluid ounce is slightly different at 28.4131 mL, a remnant of pre-metric British measurement. Common uses: US beverage container sizes (a 12-oz soda can), US liquid recipe measurements, and UK pub measures for spirits (where a 'single' is 25 or 35 mL but historically tracked from imperial fl oz).
