About Cubic Inches
A cubic inch (in³) is the volume of a cube with sides of one inch (25.4 mm), equal to approximately 16.387 mL. It is widely used in US engineering and manufacturing - engine displacement was traditionally described in cubic inches (a 350 in³ V8 engine displaces 5.7 liters), and product specifications for items sold in the US frequently reference cubic inches. Speaker cabinet volumes, wine bottle capacities in older US standards, refrigerator compartment sizes, and box shipping calculations in imperial units all use cubic inches. One liter equals approximately 61.024 cubic inches.
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 Largely superseded by millilitres but still appears in traditional compounding recipes, older US pharmacopeias, and historical medical literature. 1 fl dr ≈ 3.697 mL.
