There are TWO ways to think of THIS.I wish the world had embraced decimal angles and the 1/100000 day second. Then [...] the geographic coordinates and grids on maps would already be tied to kilometers.
(1) Time and angle could have been tied earlier: using the day of 20hx100mx100s & dividing the circle into 400-metric degrees i.e. making the 'quadrant on 100-metric degree or *gon* as I learnt later'. This defines Nautical Kilometre; as in my base paper The Metric Second (1973); or
(2) Time and angle could be tied now: using the day of 24hx100mx100s & keeping the circle of 360- degrees unchanged BUT making the 'quadrant of 90-degree and each degree further divided into 1-degree x100 arc-minutes x100 arc-seconds. This defines Nautical Kilometre; as in my posts to USMA list, where I define METRE as:
*�Metre (m') is the distance traversed by light, in vacuum, during the time interval, 1/97059575.22TH of the decimal second�. Since�1/100TH of one degree� is to be the Nautical Kilometre; length distance METRE can be seen as 1/100000th of the degree.*
What lacks had been and perhaps it may still be the 'political will' to implement?

*****The New Calendar Rhyme*****
Thirty days in July, September:
April, June, November, December;
All the rest have thirty-one; accepting February alone:
Which hath but twenty-nine, to be (in) fine;
Till leap year gives the whole week READY:
Is it not time to MODIFY or change to make it perennial, Oh Daddy!And make the calendar work with Leap Week Rule! ***** ***** ***** *****

Well, in the USA some progress is being made on the latter part of your wish -- without having to resort to the former! It's just a matter of choosing the right grid... :)

Yes, the (metric-based) *United States National Grid* survived the 2.5-year approval process and became a federally endorsed standard -- FGDC-STD-001-2001 -- in December 2001.
