Fundamntal Units Confused in the Media

This afternoon I watched a television programme about the earth's atmosphere, and was reminded why I rarely watch television programs about science. Atmopheric pressure near the earth's surface was described as 1 kilogram per square centimetre, perpetuating the pernicious confusion of force with mass.

I prefer to state atmospheric pressure at sea level as about 105 pascals. A pascal is 1 newton per square metre.
