About Teaspoons

A teaspoon (tsp) is a US customary and cooking measurement unit equal to 1/3 of a tablespoon - approximately 4.929 mL. It is fundamental to cooking and baking worldwide: nearly every recipe in US-published cookbooks uses teaspoons as the basic small measurement for spices, baking powder, vanilla, and other minor ingredients. In medicine, over-the-counter liquid medications (especially children's doses) are measured in teaspoons, with 5 mL the standard metric equivalent used on US medication labels. Three teaspoons make one tablespoon, and six teaspoons make one fluid ounce.

About Fluid Drams

A fluid dram (fl dr, also 'drachm') = 1/8 fl oz ≈ 3.697 mL. Used by apothecaries for precise medicinal compounding; a fluid dram divided into 60 minims. Largely superseded by millilitres but still appears in traditional compounding recipes, older US pharmacopeias, and historical medical literature. 1 fl dr ≈ 3.697 mL.
