Apothecaries

The traditional English apothecaries' system defines weights, not volumes. However, there was apothecaries' system for volumes too, though less commonly used. Before introduction of the imperial units, all apothecaries' measures were based on the wine gallon which later became the base of U.S. liquid gallon.

In addition to five official apothecaries' units pint, fliud ounce, fluid dram, fluid scruple, and minim, there was a set of unofficial but widely used units for various spoon and glass sizes. We list them here too.

In 1858 apothercaries' system was officially abolished in in the U.K. in favour of the standard Avoirdupois system. In the United States the apothecaries' system remained in use until 1971, when it was officially abolished in favor of the metric system.

Ship tonnage measurements

Register ton unit was defined by the Moorsom Commission (Great Britain) in 1854 to measure ship internal volume. It was officially replaced by tonnage when the International Maritime Organization (IMO) adopted The International Convention on Tonnage Measurement of Ships on 23 June 1969. Since 18 July 1994 the gross and net tonnages are the only official measures used for the ships.
