However, I think it is likely that human physical capacity has steadily decreased since the invention of the wheel and subsequently, the internal combustion engine. Driving kids to school is the latest step in this downwards path.

Nelly Dec 2012 11:20am, 4 Dec 2012 621 posts	Quote Pin Nelly Gordon, I suspect it's an eye sight issue K (capital) = 1,000 so K(capital)Mph = 1,000 x miles per hour whereas km (non-capital) = kilometer so kmph = kilometer per hour
rf_fozzy Dec 2012 11:28am, 4 Dec 2012 3,930 posts	Quote Pin rf_fozzy According to SI units, speed should always be m/s But I think conventionally, kilometers per hour is designated kph. Really, I was being facetious for the sake of comedic value, as 1000=lower case k, e.g. kilograms = kg. I'm not sure that capital K has the same meaning. It would get confused with the SI unit for temperature, which of course is the Kelvin (NOT degrees Kelvin). For reference, 0degC=273.15K (to a close approximation). 0K is absolute zero and nothing can be colder than this - it is where all atomic vibrations stop.
