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.

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.
