In Sweden, a common system for weights and measures was introduced by law in 1665. Before that, there were a number of local variants. The system was slightly revised in 1735. In 1855, a decimal reform was instituted that defined a new Swedish inch as 1 ⁄ 10 foot. It did not last long, because the metric system was subsequently introduced in ...
This is a list of obsolete units of measurement, organized by type. These units of measurement are typically no longer used, though some may be in limited use in various regions. For units of measurement that are unusual but not necessarily obsolete, see List of unusual units of measurement .

Planck units is system of geometrized units in which the reduced Planck constant is included in the list of defining constants. It is based on only properties of free space rather than of any object or particle. Stoney units is a system of geometrized units in which the Coulomb constant and the elementary charge are included.
Scottish or Scots units of measurement are the weights and measures peculiar to Scotland which were nominally replaced by English units in 1685 but continued to be used in unofficial contexts until at least the late 18th century. [citation needed] The system was based on the ell , stone , and boll and firlot .
The imperial system of measure does not have an equivalent to the US customary system of "dry measure". In the international commodities markets, the barrel ( 42 US gallons , ≈159 litres) is used in both London and New York/Chicago for trading in crude oil and the troy ounce (≈31.10 grams) for trading in precious metals, except the London ...
Like Wilkins, the names that he proposed for multiples and subunits of his base units of measure were the names of units of measure that were in use at the time. [10] The great interest in geodesy during this era, and the measurement system ideas that developed, influenced how the continental US was surveyed and parceled.
After the metric system was introduced in 1816, the word pond continued to be used, but for 1 kilogram. This doubling in size of the pond in one fell swoop created a good deal of confusion. The name "kilogram" was adopted in 1869, but the pond was only eliminated as a formal unit of measurement in 1937.
