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 While rarely used in modern commerce (having been replaced by grams in most applications), the avoirdupois dram still appears in some spice and herbalist contexts, in US gunpowder loading data (where charges are specified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 Newtons
The newton (N) is the SI unit of force, but because weight is technically the gravitational force on a mass, newtons are the scientifically correct unit for what most people call 'weight.' At standard gravity (9.80665 m/s²), 1 kg of mass exerts a weight force of approximately 9.81 N. Scales in physics labs and engineering contexts display results in newtons rather than kilograms. The distinction matters in aerospace and high-altitude contexts: an astronaut's mass stays constant at, say, 70 kg, but their weight in newtons changes from ~686 N on Earth's surface to nearly 0 N in free-fall orbit.
