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.
Cubic Meter (m³)
The cubic meter is the SI unit of volume, representing the volume of a cube one meter per side. It is vastly larger than a liter, since 1 m³ = 1,000 L. Cubic meters measure the volumes of rooms, shipping containers, refrigeration units, natural gas consumption, and water flows in hydrology and civil engineering. Because it is derived directly from the meter, the m³ integrates perfectly into other SI measurements such as density (kg/m³) and flow rate (m³/s). In industry, pricing and standards for timber, construction materials, and natural gas often use cubic meters. For environmental science, m³ is essential when modeling rainfall runoff, river discharge, or air pollutant concentrations. It stands as the backbone of large-scale volumetric measurement.
