About these units
UK Ton (Long) (ton (UK))
The British long ton equals 2,240 pounds (1,016.0469088 kilograms). Historically used throughout the British Empire, it appears frequently in naval records, early engineering documents, and historical trade ledgers. The long ton's relation to the imperial hundredweight (112 pounds × 20) makes sense within the structure of older English measurement systems. Although replaced by metric tons in the UK, it persists in maritime contexts and in interpreting historical documents. Its presence captures the complexity of pre-metric trade and the need for careful interpretation when comparing international tonnage systems.
Slug (slug)
The slug is a unit of mass in the English engineering system, defined such that a slug accelerated at 1 ft/s² experiences a force of 1 pound-force. Numerically, a slug is about 14.5939 kilograms. The slug resolves confusion between mass and force in imperial units by clearly separating pounds-force (lbf) from pounds-mass (lb). In dynamics problems involving Newton's laws, slugs provide a consistent mass measurement within the imperial framework. Although uncommon outside engineering physics education, the slug plays an important conceptual role in bridging imperial and SI thinking.
