Since gross tonnage is a bijective function of ship volume, it has an inverse function, namely ship volume from gross tonnage, but the inverse cannot be expressed in terms of elementary functions. A root-finding algorithm may be used for obtaining an approximation to a ship's volume given its gross tonnage. The formula for exact conversion of ...
Gross tonnage is a monotonic and 1-to-1 function of the ship's internal structural volume. It does not include removable objects placed outside the deck or superstructure, like the shipping containers of a container ship.
Tonnage is a measure of the capacity of a ship, and is commonly used to assess fees on commercial shipping.The term derives from the taxation paid on tuns or casks of wine. In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship.
Tonnage and displacement Gross tonnage and displacement are not equivalent and vary depending on the type of ton (e.g. metric or imperial) and how they are calculated. How gross tonnage is calculated has changed somewhat over time, but has always been a measure of cargo space (i.e., it is a measure of the volume of the cargo space), and figures ...
At 250,800 gross tons and nearly 1,200 feet long, it makes the Titanic look like a tugboat. For comparison, the Titanic was 882.9 feet long and 46,328 gross tons.
The largest may carry thousands of passengers in a single trip, and are some of the largest ships in the world by gross tonnage (GT), bigger than many large cargo ships. Cruise ships started to exceed ocean liners in size and capacity in the mid-1990s; [2] before then, few were more than 50,000 GT. [3]
In addition, the ships' deadweight tonnage (DWT) and/or gross tonnage (GT) are presented as they are often used to describe the size of a vessel. The ships are listed by type. Only ship types for which there exist a ship longer than 300 metres (1,000 ft) are included.
RMS Queen Elizabeth's size record stood for the longest time at over 54 years. This is a timeline of the world's largest passenger ships based upon internal volume, initially measured by gross register tonnage and later by gross tonnage. This timeline reflects the largest extant passenger ship in the world at any given time.
