About these units
Cab (Biblical) (cab)
A cab is a small Biblical volume measure estimated at roughly 1 liter or slightly less. It was used for grains, spices, legumes, and other dry goods. The cab appears in scriptural narratives to represent modest quantities suitable for household use or famine conditions, making it a culturally meaningful indicator of scarcity or modest provision. Its place in the Hebrew hierarchy—1 cab = 1/6 of a seah (another unit not in your list)—shows how everyday domestic needs shaped measurement scales.
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.
