About Teaspoon (tsp)

A US culinary unit of volume equal to 1/3 of a tablespoon (about 4.93 mL). Teaspoons are the smallest everyday kitchen measurement — used for salt, spices, extracts, baking powder, and pharmaceutical liquid dosing. The "5 mL teaspoon" used in medicine is a rounded form of this unit. Tsp is also the standard unit in US baking recipes for yeast, leaveners, and flavorings where precision matters more than for liquid volumes.

About Fluid Ounce (fl oz)

A US customary unit of liquid volume equal to 1/128 of a US gallon (about 29.57 mL). Fluid ounces are the standard unit on US beverage containers, shampoo bottles, cooking recipes, and cocktail recipes — a standard US soda can is 12 fl oz, a large Starbucks drink is 20 fl oz, and most cocktails call for 1.5 fl oz of spirits. Easy to confuse with the Imperial fluid ounce (~28.41 mL) used in the UK, though the difference is small enough that it rarely matters for everyday use.
