Excellent point, Bruce! I suppose they depend on the context and the requirement for speed in knots to be followed parenthetically by speed in metric units. I cannnot say whether kilotonnes ever get used or not in meteorology. I don't recall encountering them, though, in the papers I read. Jim Bruce Raup wrote: > > On 2001-08-02 22:45 -0400, James R.
