Thermocouple Table Voltage Calculator

All thermocouple voltages are given in millivolts (mV). The Seebeck coefficient (given in mV/°C) describes the slope of the reference function at the selected temperature and can be used to calculate the impact of an incremental change in temperature on thermocouple voltage.

Reference junction (cold junction) compensation

The thermocouple table values given by this calculator are based on a reference junction (cold junction) temperature of 0 °C (32 °F). If that assumption is incorrect then a voltage correction must be added to these values to compensate.
