I am more concerned over the BBC using the SI standard of speed (IEEE=20 1993)t on their news website the 'mi' unit, it took me a moment to work out= =20 that mi/hr wasn't some reference to a person in Human Resources (another=20 term I detest most violently), but actually meaning MPH. I also object most= =20 strongly to the unit Hertz, I think kcs (kilo cycles per second) far more=20 intuitive. To cap it all they also have mixed their units in the news report,=20 reporting speed in metric as km/s, and then converting that to MPH for=20 proper measurement. :) For reference purposes:=20 http://www.ewh.ieee.org/soc/ias/pub-dept/abbreviation.pdf Of course using the SI unit is correct, but i can't think of anyone outside= =20 a scientific environment who wouldn't use mph in the real world when=20 referring to imperial speed measurement. I'm going to be annoyed for the rest of the day now!
