The standard platinum resistance thermometer has the characteristics of high accuracy and good stability when measuring under production conditions,and is widely used to transmit the international temperature scale and temperature measurement.In order to realize the conversion of resistance value and temperature,this paper intro-duces the determinant to analyze and deduce the problems of function operation and related data parameters in the conversion,and obtains the a、b、c and a and b values at(0～660.323)℃ and(0～419.527)℃,and the con-version process between the measured resistance value and temperature value is provided at last.
