What is a gross ton?

A gross ton is a unit of weight used to measure the total weight of a ship or aircraft, including its cargo, passengers, fuel, and other equipment. It is equal to 2,240 pounds or 1,016.05 kilograms.

Gross tonnage is not the same as displacement, which measures the weight of the water displaced by a ship's hull. Gross tonnage is used to determine a vessel's registration, fees, and taxes, and is also a factor in the calculation of crew size and safety regulations.

Gross tonnage can be further divided into two categories: gross registered tonnage (GRT) and gross tonnage (GT). GRT is used for smaller ships, while GT is used for larger ships and aircraft.

Overall, gross tonnage is an important metric in the maritime and aviation industries, as it helps to ensure safety and proper regulation of vessels and aircraft.
