ship tonnage measurement

Ship tonnage measurement quantifies a vessel’s size and cargo capacity, but not its weight. There are two main types: gross tonnage (GT) and net tonnage (NT). Gross tonnage reflects the total internal volume of a ship’s enclosed spaces, used for safety and regulation purposes. Net tonnage represents the volume available for cargo and passengers, indicating how much freight a ship can carry. These measurements are calculated using specific formulas based on the ship’s internal dimensions, providing a standardized way to assess ship size for regulatory, safety, and commercial reasons.
