ABSTRACT
The method of performing Tolerance Stackups taught in this text requires all dimensions
and tolerances to be converted into equal bilateral format.
This chapter describes the techniques for converting plus/minus dimensions and
tolerances into the equal bilateral format. This is necessary for all dimensions and
tolerances, whether they are plus/minus or GD&T. Conversion of Geometric Dimensions
and Tolerances into equal bilateral plus/minus toleranced dimensions will be discussed in
Chapter 9. Whether dealing with U.S. inch or metric dimensions and tolerances, linear or
angular units, the technique for conversion is the same.
