About Avoirdupois Drams
An avoirdupois dram (dr av) is 1/16 of an avoirdupois ounce - approximately 1.772 grams. Part of the avoirdupois system that governs everyday trade weights in the UK and US, it was historically used to measure small quantities of goods and spices in commerce. While rarely used in modern commerce (having been replaced by grams in most applications), the avoirdupois dram still appears in some spice and herbalist contexts, in US gunpowder loading data (where charges are specified in grains and drams), and in archaic recipe books.
About Slugs
A slug is a unit of mass in the British imperial and US customary foot-pound-second (FPS) engineering system, equal to the mass that accelerates at 1 foot per second squared under a force of 1 pound-force - approximately 14.594 kg. The slug was introduced to simplify dynamics calculations in engineering: using slugs ensures that F = ma holds without unit conversion factors when force is in pounds-force and acceleration in ft/s². Aerospace engineers and mechanical engineers working in US customary units use slugs for aircraft mass, structural dynamics, and ballistic calculations.
