Abstract: In three earlier papers, it has been shown, that the conventional treatment of piston gage calibration data to determine effective, A, and subsequent use of A to calculate pressure, P, from force, F, impressed on the piston leads to non-constant values of A. Conventionally, A is the ratio F/P. In the earlier papers, it was shown that the relationship between P and F was represented much better by an equation of the form P a + bF derived from linear least squares analysis of calibration data. In the present paper, calibration data for 10 piston gages were analyzed to produce linear and quadratic equations relating P to F. These equations are shown to be much more efficient for calculating pressure, P, from force, F. Detailed analysis will be presented.
