Stephen, Use a normal plural convention, 229 kelvins, just as you would for lengths, 229 meters. As I said in my post, but briefly, a change occurred in 1968. Degrees kelvin were replaced by kelvins. Yet, these changes usually take time to filter down to the schools for various reasons. Teachers are not inclined to monitor this activity at the CGPM. The information in textbooks is already several years old by the time the textbooks are released. Some teachers teach the same thing they did when they first started teaching up to 30 years earlier. When I entered high school in 1960 they were still using degrees centigrade and only then starting to make the transition to degrees Celsius. Yet the CGPM made that change in 1948. Jim "Stephen C.
