Net tonnage is used to calculate the port duties and should not be taken as less than 30 per cent of the ship's gross tonnage. [2] Net tonnage is not a measure of the weight of the ship or its cargo, and should not be confused with terms such as deadweight tonnage or displacement. Also, unlike the net register tonnage, the net tonnage is ...
Gross tonnage, along with net tonnage, was defined by the International Convention on Tonnage Measurement of Ships, 1969, adopted by the International Maritime Organization (IMO) in 1969, and came into force on 18 July 1982. These two measurements replaced gross register tonnage (GRT) and net register tonnage (NRT). Gross tonnage is calculated ...

Net register tonnage (NRT, nrt, n.r.t.) is a ship's cargo volume capacity expressed in "register tons", one of which equals to a volume of 100 cubic feet (2.83 m 3).It is calculated by subtracting non-revenue-earning spaces i.e. spaces not available for carrying cargo, for example engine rooms, fuel tanks and crew quarters, from the ship's gross register tonnage.

Net tonnage is a dimensionless index calculated with a mathematical formula. While this template allows, for the sake of backwards compatibility, the use of "tons" as the unit for net tonnage, this is not correct and should not be used in future articles.
(Merchant ships display gross tonnage ; see tonnage), deadweight and the number of items it can carry i.e. TEU 20 ft equivalent units. Displacement is expressed in tonnes (metric unit). Displacement of a ship built for the US is in long tons, Warships are shown in displacement tons or tonnes. To preserve secrecy, nations sometimes misstate a ...
Gross register tonnage (GRT, grt, g.r.t., gt), or gross registered tonnage, is a ship's total internal volume expressed in "register tons", each of which is equal to 100 cubic feet (2.83 m 3). Replaced by Gross Tonnage (GT), gross register tonnage uses the total permanently enclosed capacity of the vessel as its basis for volume.
