But Anders Celsius got it a bit wrong in 1741 there in the beginning, putting 0 degrees to the boiling point and 100 degrees to the melting point of ice. Fortunatly that misstake was corrected sometime after his death in 1744. :) Some rumours say it was actually Linné (another Uppsala gigant) that corrected it, but it cannot be prooven. > > I far prefer to be able to convert effortlessly between units, than to > > embedd arbitrary material properties in my measurement units. > > It would have been just as easy to achieve this simplicity with a metric > system based on pounds, inches and seconds...

We would be running of the royal french inch, some 27,07 mm. :) Cheers, Magnus _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
