The 13th meeting of the Conf�rence g�n�ral des poids et mesures (CGPM), 1967-1968, decided 1, the unit of thermodynamic temperature is denoted by the name "kelvin" and its symbol is "K"; 2, the same name and the same symbol are used to express a temperature interval; 3, a temperature interval may also be expressed in degrees Celsius That answers your first question. The answer to your second question is that they are the same. Your third question is incorrect, as you suspected. Joe Joseph B. Reid 17 Glebe Road West Toronto M5P 1C8 Tel. 416 486-6071
