About Apothecary Drams
An apothecary dram (dr ap) equals 3 scruples or 60 grains - approximately 3.888 grams. Part of the traditional apothecary system used by physicians and pharmacists from the Middle Ages through the 19th century, it was the standard unit for prescribing and dispensing medicines. Prescriptions written in the apothecary system used special symbols: the dram symbol (℈) and ounce symbol (℥) appear throughout historical medical records and old pharmacy ledgers. The apothecary dram differs from the fluid dram (a volume unit) and from the avoirdupois dram.
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.
