About Long Hundredweights

A long hundredweight (long cwt) equals 112 pounds or approximately 50.802 kg - equal to 8 stone. The standard hundredweight in the United Kingdom and much of its historical trading sphere, it reflects the medieval English stone of 14 lb (8 × 14 = 112). British agricultural commodity prices, wool trade records, and livestock market reports historically used long hundredweights. The UK meat trade still occasionally references hundredweights in wholesale pricing.

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.
