A quick check of Wikipedia states: (http://en.wikipedia.org/wiki/Celsius http://en.wikipedia.org/wiki/Celsius) Why technical articles use a mix of kelvin and Celsius scales In science (especially) and in engineering, the Celsius scale and the kelvin are often used simultaneously in the same article (e.g. "…its measured value was 0.01023 °C with an uncertainty of 70 µK…"). This practice is permissible because: the degree Celsius is a special name for the kelvin for use in expressing Celsius temperatures, and the magnitude of the degree Celsius is precisely equal to that of the kelvin So based on that, it is permissible to do 0C == 273.15K.
