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 .
Multiples and submultiples of metric units are related by powers of ten and their names are formed with prefixes. This relationship is compatible with the decimal system of numbers and it contributes greatly to the convenience of metric units. In the early metric system there were two base units, the metre for length and the gram for mass. The ...

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.
The basic unit of area was the tir-cumaile, "land of three cows", as it was an area of land that was at some point worth three cows.It is sometimes erroneously interpreted as the area needed to graze three cows, but it is far too large for that; in modern Ireland, a cow grazes on about 0.4 ha, so twenty or more could graze a tir-cumaile.
