Six methods are given for converting to temperatures the measured values of emf generated by thermocouples. Two are based on the use of thermocouple reference tables alone. Two are based on the use of calibration data alone. And two are based on a combination of calibration data with reference table functions. It is shown that one method is preferred if graphical presentation is required, while another is clearly the best for computer conversions of thermocouple emf to temperatures.
