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 Liter (L)
A metric unit of volume equal to exactly 0.001 cubic meters (one cubic decimeter), defined by the BIPM since 1964. The litre is accepted for use with the SI per the BIPM SI Brochure and is the global standard for beverages and beverage labelling under the EU Food Information to Consumers Regulation 1169/2011 and Codex Alimentarius, fuel economy (km/L outside North America), automotive engine displacement (e.g., '3.0 L turbo'), medical fluid volumes (TPN bags, IV fluids, blood volume), industrial chemical-process material balances (Aspen HYSYS / CHEMCAD default volumetric unit alongside m³), and HVAC/plumbing flow specs. Reference values: a standard wine bottle is 0.75 L, a Coke can 0.33 L, a US half-gallon ~1.89 L, a midsize-car fuel tank 50-70 L, a household water heater 150-300 L, a standard IBC industrial-chemical tote 1,000 L. One litre of pure water at 4 °C and 1 atm weighs almost exactly 1 kg — a deliberate design feature of the original metric system. 1 L = 1,000 mL = 1,000 cm³ = 1 dm³ = 0.2642 US gal = 33.81 US fl oz.
