Koku was also used to measure how much a ship could carry when all its loads were rice. Smaller ships carried 50 koku (7.5 tonnes, 7.4 long tons, 8.3 short tons) while the biggest ships carried over 1,000 koku (150 tonnes, 150 long tons, 170 short tons). The biggest ships were larger than military vessels owned by the shogunate.
A quire of paper is a measure of paper quantity. The usual meaning is 25 sheets of the same size and quality: 1 ⁄ 20 of a ream of 500 sheets. Quires of 25 sheets are often used for machine-made paper, while quires of 24 sheets are often used for handmade or specialised paper of 480-sheet reams.
Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage).

The average design ship speed for bulk carriers of Handysize and above is 13.5–15 knots (25.0–27.8 km/h; 15.5–17.3 mph). [23] The propeller speed is relatively low, at about 90 revolutions per minute, although it depends on the size of the propeller.
A handymax ship is typically 150–200 m (492–656 ft) in length, though certain bulk terminal restrictions, such as those in Japan, mean that many handymax ships are just under 190 meters (623 ft) in overall length.
The WindWings sails measure 37.5 metres (123 feet) in height, dwarfing the Pyxis Ocean’s bridge but only taking up a relatively small space of the ship’s cargo holds.
Bulk Phosphate Stowage Factor (SF) about 0.90 m 3 /ton (32 ft 3 /ton) In fact, Ship A has space for 55,000 mtons on her holds 70,000/0.90 = 77,000 mtons or 2,470,000/32 = 77,000 mtons (rounded) However, Ship A can only take 55,000 mtons in weight of Bulk Phosphate before Ship A loadline is submerged Stowage Factor (SF) Example 2: Ship B
