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 Largely superseded by millilitres but still appears in traditional compounding recipes, older US pharmacopeias, and historical medical literature. 1 fl dr ≈ 3.697 mL.

About Cups

A cup = 8 fl oz = 16 tbsp ≈ 236.6 mL - the fundamental unit of American cooking. Almost every US recipe uses cups for dry and liquid ingredients. The US customary cup (236.588 mL) differs from the US legal cup (240 mL, used in nutrition labelling) and the metric cup (Australia/Canada: 250 mL). Kitchen sets come in 1/4, 1/3, 1/2, and 1 cup sizes. 2 cups = 1 US pint.
