THERMAL CONVERSION CALCULATOR


CUI’s thermal conversion calculator can be used to quickly convert between common units for thermal resistance, specific heat, thermal conductivity and thermal conductance. To use the calculator, enter your value into one of the four thermal conversions, select your units, click calculate and the converted units will be shown.
