Tonnages is a noun that refers to the total weight or carrying capacity of a ship, aircraft, or vehicle. It is often used to describe the amount of cargo that can be loaded onto a vessel. The term can also be used to measure the overall weight or capacity of a fleet or group of vehicles.
In shipping and maritime industries, tonnages can be categorized into different types, such as gross tonnage (GT) and deadweight tonnage (DWT). Gross tonnage refers to the entire internal volume of a ship, including crew quarters, cargo holds, and other spaces, and is used as an indicator of a vessel's size. Deadweight tonnage, on the other hand, measures the maximum weight of cargo, fuel, and supplies that a ship can carry safely, excluding the weight of the ship itself.
The concept of tonnages is also relevant in aviation, where it indicates the maximum takeoff weight or payload capacity of an aircraft. It determines the aircraft's ability to transport passengers, baggage, and cargo, while taking into account fuel, crew, and other necessary equipment.
Overall, tonnages are a crucial factor in logistics and transportation industries as they provide a standardized unit of measurement for the capacity and capabilities of various modes of transport.
The word "tonnages" is derived from the word "tonnage".
The etymology of "tonnage" can be traced back to the Old French word "tonnage", which ultimately comes from the Late Latin term "tonnaticum". This Latin term referred to the payment or duty imposed on a vessel based on its weight or capacity.
In turn, "tonnaticum" is derived from the Late Latin word "tonnus", meaning "cask" or "tun", which itself originated from the Greek word "tonnos", meaning "tree-trunk" or "barrel". This reflects the idea of measuring a ship's capacity by the number of barrels or casks it could carry.
Over time, the term "tonnage" has evolved and is now used to refer to the measure of cargo or freight capacity of a vessel, usually measured in tons.
