The primary objective in preparing a new edition of Principles of Farm Machinery at this time was to incorporate SI (metric) units of measure. Engineering colleges and schools in many universities are moving rapidly toward the use of the SI system in teaching engineering courses. In this Third Edition U.S. customary units are also shown in most places because responses to a questionnaire sent to all agricultural engineering departments in the United States and Canada were overwhelmingly in favor of the dual-unit presentation. Customary units have been omitted in some places where the significance of the numbers is in their relative values rather than their absolute magnitudes or where including dual units would unduly complicate the presentation of a graph. Problems have only SI units.
