/* Reasoning for not converting between degree fahrenheit, degree celsius
 * and kelvin: 
 *
 * Typically temperatures are absolute values that don't get
 * summed up. So let everybody use the unit he is happy with.
 * Of course there are also temperature differences, but these need 
 * a different conversion formula than absolute temperatures, thus making
 * a mess which could only be resolved by introducing additional units.
 *
 * At least this is what I guess that the original author intended.
