The metric system

Mètre Paris
In full revolution, the French National Assembly accepted during the 1790’s the proposal by the French Academy of Sciences that the definition of a metre should be one ten-millionth length of the Earth’s meridian, the distance from the equator to the North Pole. The metre as a universal measurement was internationally agreed by the end of the 19th century and as a “compensation” the French agreed to abandon “Prime Meridian”, which passed through Paris, to the benefit of Greenwich. (See my post Sept. 10th.)
I visited the Luxembourg Gardens yesterday and when I left, just across the street, I happened to see the above “metre” in an arcade of a building occupied by the French Agency for Weights and Measurements (l’Agence des Poids et Mesures). (The address is 36 rue Vaugirard, 6th arrdt.) I learnt that this is the only remaining “metre” still in place out of the 16 that were placed around Paris in 1796-97 in order to make the population acquainted with this new way of measuring.
The metre is still basically the same, but is today defined as equal to the distance traveled by light in vacuum during 1/299792458 of a second!!
One issue is still whether I shall write metre (UK) or meter (US)?
Another more important issue is obviously that the metric system is not yet generally applied! Imagine that in all my posts about e.g. altitudes and distances, I feel obliged to translate all measures to yards, feet, miles…!!
In 1960, at last, the metric system was officially recognized by almost all countries and this decimal based agreement covers not only length measurements, but also mass, temperature… When will it ever be really implemented, not only by scientists? I imagine that some of you feel “guilty”!
… and if I now proposed a specific "international agreement" between bloggers to communicate in metres, kilograms, centigrades… ? As not only the metre, but also the kilogram are French inventions and the centigrade (Celsius) a Swedish invention, I feel of course particularly concerned!

All nice things come unfortunately to an end; time to go back to Paris – of course also quite nice!
