And what is more, 'mesures uselles' can be translated as 'customary units'. It 
was also called 'systeme metrique usuel - metric customary system'.
According to the myth Napoleon metricated Europe. When I started to reseach 
Dutch metrication years ago l suspected that Napoleon had in fact nothing to do 
with it. Then, when studying the archives, I found out what Napoleon had really 
done. The decree that made these bastard units legal (the Imperial Decree of 
1812-02-12, next year is its 200th anniversary) talked about 'instruments de 
mesure - measuring instruments' to be brought in with subdivisions
adapted 'au besoin du people - to meet the needs of the people'.
In 1816-02-21, the use of the decimal metric system was banned in the retail 
trades. The metric system seemed to be making its 'last stand at the Alamo!'. 
The reforms of the calendar and time had already failed. Yet in the same year, 
1816, The Netherlands decided to go metric by law of August 21. These six 
months in 1816 were the nadir of the metric system! 
The tide slowy turned and the ban was revoked in 1825. In the autumn of 1836, 
an all out metric counter offensive started, and ended in 1837 with a 
resounding victory and complete French metrication: the 'Loi du 4 Julliet 1837 
concernant les Poids et Mesures'.
I wonder what would have happened if these units had not been adopted in 
France. I think that the USA and the UK would have gone metric in the 19th 
century. 
Yes, Napoleons 'systeme metrique usuel', carried on in its Anglo-Saxon 
versions, is still with us!

  Whatever "US Customary" is!


  I understand that US Customary is fully metric at this time in 2011 since all 
the old measuring words (such as inch, ounce, pint, mile, pound, and ton) have 
all been defined by metric system units since 1959 or 1893.


  Currently, US Customary measuring words have the same status that Napoleon's 
"mesures usuelle" had between 1812 and 1839. 


  US Customary is just a way to use new definitions -- that never existed 
before 1893 or 1959 -- to protect some old measuring words to which many, 
perhaps most, of the citizens of the USA have become accustomed and think they 
understand.


  In short (to paraphrase John Steele) many, perhaps most, citizens of the USA 
also "have a poor understanding of US Customary."
