The international
inch is defined in terms of the metric (!) system of units
to be exactly (!) 25.4 mm. This definition was agreed
upon by the U.S. and the British Commonwealth in 1958.
Prior to that, the U.S. and Canada each had their own,
slightly different definition of the inch in terms of
metric units, while the U.K. and other Commonwealth countries
defined the inch in terms of the Imperial Standard Yard.
The U.S. continued to use its previous national definition
of the inch for surveying purposes. This inch, known as
the U.S. survey inch is defined so that 1 metre is exactly
39.37 survey inches. 1 survey inch equals approximately
25.40000508 mm, or 1.000002 international inches.
