The unit of mass in mathematics is tons, which is often used to measure the weight of larger items in life. One ton is equal to 1000 kg.

Conversion of unit conversion:

1 0,000 ng = 1 μ g

1 0,000 μ g = 1 mg

1 1,000 mg = 1 g

1 0,000g (g) = 1 kg (kg)

1 0,000 kg = 1 ton

Weight ton refers to the weight of the ship, and can also indicate the load capacity of the ship. Weight tons can be divided into displacement and load capacity.

Displacement: refers to the weight of the same volume of water discharged by a ship in the water, including full displacement, no-load displacement and displacement. The former refers to the displacement of the ship when it is fully loaded with goods, personnel, fuel, fresh water and replenishment, and there is a specified safe freeboard, while the latter usually refers to the displacement of the ship when it reaches the summer load line in seawater; The latter refers to the displacement when the ship is not loaded with goods, personnel, fuel, fresh water and supplies.

Deadweight: refers to the deadweight of a ship, which can be divided into total deadweight and net deadweight. The former refers to the sum of the weight of goods, personnel, fuel, materials, fresh water and other reserves required for a single voyage.

Namely: total load = full load displacement-no load displacement; The latter refers to the tonnage of loaded goods, which varies with the spare parts reserve required for a specific voyage. Therefore, the reserve of spare parts should be reduced as much as possible in each voyage to obtain the maximum net load, that is, net load = total load-the weight of fuel, fresh water, supplies and materials.
