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.
Cup (UK) (cup (UK))
A UK cup equals 284 mL, slightly larger than both the US cup and the metric cup. Used historically in British cooking, the UK cup is now largely superseded by grams and milliliters, but it remains relevant when interpreting older recipe books and culinary traditions. Its intermediate size provided a convenient measure in a pre-metric world and still appears in baking communities that prefer imperial standards.
