Bill Potts said:- | The SI derived unit (not "derivative") for pressure is pascal (Pa). Hecto | and kilo are both valid prefixes.

Hectopascals are the standard here - in fact our local radio announcer makes it easy on the ear - every day he says things like "and old Hector says its going to be 1016 hectopascals today". Mike
