About these units
Ton Register (ton reg)
A register ton, or ton register, is a unit of volume, not mass, equal to 100 cubic feet. It is used in maritime contexts to measure the internal capacity of ships—specifically cargo-carrying volume, not weight. Ship registries rely on register tons to calculate taxes, port fees, and cargo classifications. The unit dates back to 19th-century maritime law, where consistent volumetric measurement was critical for international shipping regulation. Despite changes in global trade and containerization, register tons remain important for historical vessel documentation, as well as for understanding older merchant and naval ship specifications.
Deciliter (dL)
A deciliter, 1/10 of a liter, appears prominently in medical diagnostics—especially in blood testing. Many laboratory measurements use dL as the denominator, such as mg/dL for blood glucose or cholesterol levels. In Europe, food packaging sometimes lists nutritional values per deciliter, especially for dairy products and soups. The dL is just large enough to be meaningful while still small enough for dietary and medical precision. Though not as common as liters or milliliters, the deciliter serves specialized roles where moderate scale and medical tradition intersect.
