 I'm in two minds on the kilopascals vs 
 hectopascals/millibars argument. Whilst from a 
 scientific point of view I'd like to see the SI 
 unit, or a  10 factor of it used, it must be 
 said that a significant change in pressure is of 
 the order of 1 hectopascal/millibar, seeing it 
 buried somwhere right of a decimal point could, to 
 some, make it seem less significant.
