About Milliliter (mL)
A metric unit of volume equal to exactly one thousandth of a litre (0.001 L) and exactly one cubic centimeter (1 mL ≡ 1 cm³ per BIPM). The mL is the universal small-volume unit in clinical medicine and pharmacy (USP / EP / JP / BP / IP pharmacopoeial dosing per ISO 13485 medical-device standards), laboratory chemistry (titration burettes, analytical glassware per ASTM E542), small-batch cooking outside the US, perfume and personal-care products (EU Cosmetic Regulation requires labelling in mL), and beverage packaging (a 500 mL water bottle, 750 mL wine, 700 mL standard spirits bottle in most of the world / 750 mL in US). Reference values: a typical Luer-lock medical syringe 1-60 mL, US shot glass ~44 mL (1.5 fl oz), standard saline IV bag 250-1,000 mL, espresso shot ~30 mL, retail vape juice 30/60/120 mL. In medical and laboratory contexts, mL and cc (cubic centimeters) are used interchangeably — both equal one cm³.
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.
