The thermoelectric reference tables for the most common thermocouples are shown below. For each type of thermocouple we show first the general polynomial, followed by the table of coefficients and by the explicit polynomials for both the direct and inverse use. The output of the direct polynomials is in microvolts (μν). Output of the inverse polynomials is in degrees Celsius (°C). The index 90 indicates the standard used (in this case the International Temperature Scale of 1990 [ITS-90]).
