Incorrect unit name

[James R. Frysinger]

In Table 8 the statute mile is defined as 5280 international feet. Rather, that is the international mile. The statute mile is defined as 5280 survey feet.

History: After the 1959 international agreement changed the definition of the foot in the US to be 0.9144 m exactly, surveyors and civil engineers complained that volumnious legacy surveys and so forth used the previous definition of (1200/3937) m and that this change would be disruptive. So, by statute, Congress created a survey foot of (1200/3937) m (the old 1893 Mendenhall Order definition). Thus, by statute, miles used in surveying are referred to as statute miles of 5280 survey feet each. The fathom, rod, and furlong are likewise based on the survey foot, as I understand things.

Yes, to be fixed. Thank you.

Fixed. The international mile is now just called mile. The survey lengths are also called statute and the historical explanation is added as commentary under these US survey lengths.
