Dear Jim,
I have a feeling that, some time ago, you referred to SI as the sixth metric
system. Is this so, and if so how do you count the various historical metric
systems.
My counting goes:
1 Original metric system 1795
2 cgs metric system of about 1872
3 metric system of the 'Treaty du Metre' in 1885
4 Giorgi's mksA metric system of 1901
5 Modern metric system known as SI of 1960 with developments from 1948.
