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.
Kiloliter (kL)
A kiloliter equals 1,000 liters, identical to 1 cubic meter, and is used in water management, municipal planning, agriculture, and commercial storage. Utility companies measure household water usage in kiloliters. Irrigation requirements, swimming pool volumes, and cistern capacities are also commonly expressed in this unit. Its equivalence to the cubic meter gives it flexibility—metric engineers may prefer m³, while public-facing documentation may use kL for clarity.
