DWT stands for deadweight tonnage. It is **the sum of the weights of cargo, fuel, and provisions that a ship carries**. It is expressed in tonnes with respect to the ship’s carrying capacity. DWT is subject to the ship’s capacity, speed, years in service, as well as the number of passengers and crew.

TEUs are 20-foot equivalent units. They represent the cargo capacity of a standard container of 20 feet length. One 20-foot container of cargo is counted as one TEU. If the container is 40 feet long, it represents two TEUs.
