Sirs: >.....Ther you are – blame it on our duodecimal clocks.
NO, I think, it was Napoleon's agreeing for his coronation and later Cote d'Or - if I am right - who agreed to go ahead for 'metrication' ignoring the pressing for linking Time measure with Length Unit - that caused and left the continued confusion for implementing cgs, MKS, and later MKSA or Le Systeme Internationale d'Unites to remain *back bencher*. It was the Calendar - time measure - arc angle that left 'isolated' to be done independently and Sea Power of the British Fleet that did not permit Nautical Kilometre to be accepted, in technology.

In the 1870’s when time zones were first being introduced a choice had to be made regarding the prime meridian – there were two candidates – Greenwich and the French equivalent. At the time the best maps were British and that swung the day. Also, clocks had 12/24 hours, not 10, so 360° was a better choice than 400. Ther you are – blame it on our duodecimal clocks. From: [email protected] [mailto:[email protected]] On Behalf Of Pat Naughtin Sent: 07 June 2010 06:37 To: U.S. Metric Association Subject: [USMA:47527] Nautical measures On 2010/06/06, at 17:12 , Martin Vlietstra wrote: For many years the Daily Telegraph quoted the height of high tide at Dover in feet without the benefit of a metric conversion, even though the height indicator at the Dover docks was only in metres, the admiralty charts were in metres and the published tide tables were in metres. Dear Martin, One of the (several) reasons that the French metric committee chose to use the Earth as a standard for the length of the metre was that they lived in an age when shipping and world exploration were extremely important issues. They intended that the measuring of angles in grades and the measuring of distances in metres and kilometres would drastically reduce the complexity of nautical calculations. Consider a quadrant of the Earth divided decimally. 1 quadrant = 100 grade = 10 000 kilometres 0.1 quadrant = 10 grade = 1000 kilometres 0.01 quadrant = 1 grade = 100 kilometres 0.001 quadrant = 0.1 grade = 10 kilometres 0.000 1 quadrant = 0.01 grade = 1 kilometres etc. Unfortunately sailors decided not to go with the simplicity of the decimal metric system so the transition to the metric system didn't work so far (from 1770 till 2010). People 'who go to the sea in ships' still cling to the pre-1770 measuring words. They continue to use: nautical miles for distance knots for for wind speed knots for vessel speed feet for vessel length inches for rope diameter etc. Perhaps your example is simply another example of irrational conservatism.
