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.
Tablespoon (UK) (tbsp (UK))
The UK tablespoon traditionally equals 15 mL, though older definitions ranged from 17.7 to 25 mL depending on period and context. In modern British cooking, the tablespoon is standardized at 15 mL, aligning it with the metric tablespoon used in many countries. This measure remains essential in culinary arts for oils, spices, flavorings, and liquid ingredients, demonstrating how some units survive because of convenience and cultural familiarity, even in highly metricized societies.
