Hmm, I used to think both k and K were accepted for kilo, but I can't find anything that says K is accepted for use as kilo.
All the symbols in SI units have to be distinct, as combined units are units also. Consider: kWh = kilo-watt-hour = 3.6 MJ Nm = newton-metre The capital K is used for kelvin. So Km = kelvin-metre, which I suppose would be the unit to measure the total temperature over a length (product of temperature and length). Sure, most people can guess what you mean from the context but that doesn't make it right... Have a nice day, -- Martijn van Oosterhout <kleptog@gmail.com> http://svana.org/kleptog/
