bill aycock of persimmon hill kindly corrected me (off list) about my WRONG
definition of specific gravity.
specific gravity is defined as the ratio of the mass of a volume of matter
to the mass of an
identical volume of water at a specified temperature, and hence, is
so, my mumbling about specific gravity in the previous post was wrong from
the start :)

i should teach (to myself) how to find correct definitions first before to
discuss UNIT and DIMENSIONS.
shame-shame (to myself).
