However, not aware of knots changing even before 1980 or any time in the 20th century.
1929 for the definition of the international nautical mile as 1852m, adopting the French navy standard from 1906. There were hold-outs who stuck with their older definitions though - US with 6080.2ft until 1954 and UK with 6080ft until 1970.

Edit: I was interested in how the distance of 1 minute of arc changed with out understanding of the size and shape of the earth over time, so went looking.

What I referred to was 'Landmile' vs. 'Nauticalmile' as we used to call it here.

According to Wikipedia it's "Static Mile" (1.6 km) and "Nautical Mile" (1.8 km).
(Dot for imperials, must be substituted by comma in other states/countries).

SIgh ...
 
Well, there is the exact 1852 meters per nautical mile… :cool:
Close, but not quite exact I don't believe. As the nautical mile is currently defined as 6076.11549 feet. There are some conventions that do call it exactly 1852 meters. There isn't this disagreement with the 2.54 cm to inch convention.

Also, -40 degrees is true at the one temperature, but the conversion for the size of a degree is not exact.

Hopefully I've used up my daily allotment of pedantry now. ;)

Hmm.
You may have to wait 'til your next birthday to get persnickety again...
