Zusammenfassung:	A method of obtaining a linear curve fitting conversion equation for use with a non-linear measurement system is provided. The linear curve fitting conversion equation converts a subject value entered into the non-linear measurement system into a measured value for simulating a linear curve. The method includes substituting a known preset input value, an output value generated by entering the preset input value into the non-linear measurement system, and n operator settings falling within the measurement range of the non-linear measurement system into a (n-1)th order polynomial to form simultaneous equations including n polynomials and thereby obtain a fitting parameter for creating the linear curve fitting conversion equation for use with the non-linear measurement system, thereby dispensing with the hassles of processing a large amount of data required for creating a conversion rule.
