About these units
Ton Register (ton reg)
A register ton, or ton register, is a unit of volume, not mass, equal to 100 cubic feet. It is used in maritime contexts to measure the internal capacity of ships—specifically cargo-carrying volume, not weight. Ship registries rely on register tons to calculate taxes, port fees, and cargo classifications. The unit dates back to 19th-century maritime law, where consistent volumetric measurement was critical for international shipping regulation. Despite changes in global trade and containerization, register tons remain important for historical vessel documentation, as well as for understanding older merchant and naval ship specifications.
Minim (US) (minim)
The US minim is defined as 1/60 of a US fluid dram, approximately 0.0616 mL. Similar to the UK minim, it originated in apothecary practice as a standardized alternative to the inconsistent "drop." Minims were used heavily in 18th–19th century American medicine for dosing tinctures, opiates, essential oils, and concentrated extracts. Although it has disappeared from modern pharmaceutical practice, the minim remains relevant for studying early American medical traditions and the evolution of clinical measurement.
