About Quarters
A quarter (qr) in the avoirdupois system equals 28 pounds or one quarter of a hundredweight - approximately 12.70 kg. Historically, quarters were used in British trade for measuring grain, wool, and other bulk commodities. The British quarter of grain (28 lb) was the standard purchase quantity at markets and mills throughout medieval and early modern England. In the US, the term 'quarter' sometimes refers to a quarter of a short hundredweight (25 lb) rather than the British 28 lb.
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.
