James L. Cook : Conversion Factors

This is a handy reference for students, teachers, and practitioners in the sciences and technical subjects, especially engineering and physics. More than 3500 conversion factors are given directly. Calculated from internationally agreed upon primary conversion factors, all factors are given to the greatest possible accuracy within a limit of ten significant figures. The conversion factors are grouped into unit types by areas of application, ranging from angular acceleration to volume flow. The primary conversion factors used in deriving all the others are given in separate sections. Also of practical help are sections of common mathematical and engineering formulae together with numerical values of certain common material properties (strengths, densities, and thermal properties).
