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.
Stere (st (vol))
A stere is exactly 1 cubic meter, but with a particular association: it was defined specifically for measuring stacked firewood. Logs are irregular, so the stere measures the approximate space that a cubic meter of stacked wood occupies (including air gaps). The stere is still used in France and some other European regions as part of forestry traditions. Firewood sales often use the stere to maintain consistency with historical practices. The stere's survival shows how volume measurement often reflects cultural and economic tradition rather than purely scientific convenience, especially in long-standing industries like wood harvesting.
