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 (UK) (minim (UK))
The UK minim is one of the smallest traditional volume units, equal to 1/60 of a dram, or roughly 0.059 milliliters. Introduced in the early 19th century to replace the inconsistent "drop," the minim allowed physicians and pharmacists to dose potent liquid medicines more reliably. Before modern syringes and droppers, apothecaries needed a precise micro-unit that could be measured using graduated glassware. The minim served this purpose exceptionally well and was foundational in early medical standardization. Although no longer used in contemporary medicine, it remains historically important, especially in pharmacology, toxicology, and the study of pre-modern medical practice.
