The reason that the unit of mass has the prefix "kilo" is that the metric
system originally had "milli" as its smallest prefix. The evolution was as
follows:

Académie des Sciences  Décret du 1er août  Décret du 7 avril    SI
        1792                  1793               1795
     ----------            -----------       -----------      ---------
      millier               bar                 --             mégagramme
        --                  décibar             --                --
        --                  centibar          myriagamme          --
      grave                 grave             kilogramme       kilogramme
      décigrave             décigrave         hectogramme      hectogramme

      milligrave            gravet            gramme           gramme

        --                  centigravet       centigramme      centigramme
        --                  milligravet       milligramme      milligramme

The above is based on "Le Système Métrique", 1975, by H, Moreau.

Primarily because the rest of the world uses a 24-hour day.  Als with a
decimal day an 8-hour shift becomes a 3.333-hour shift.
