Definition
- Noun:
- A unit of mass: A "gross ton" is a British imperial unit of mass equal to 2,240 pounds (approximately 1,016.05 kilograms). It is also known as a "long ton."
Usage
- The "gross ton" is primarily used in the United Kingdom and some Commonwealth countries for measuring large masses, such as the displacement of ships or the weight of heavy commodities.
- It contrasts with the "short ton" (2,000 pounds) used in the United States and the metric "tonne" (1,000 kilograms).
Examples
- Noun:
- The ship's displacement was measured at 15,000 gross tons.
- The cargo of coal weighed over 500 gross tons.
Advanced Usage
- "Gross register tonnage (GRT)": A related but distinct maritime term. It is a measure of a ship's total internal volume, where one gross register ton is equal to 100 cubic feet. Although it contains the word "ton," it is a unit of volume, not mass. The "gross ton" (long ton) may be used in calculations related to a ship's weight or displacement, while GRT refers to its enclosed space.
