AIHA supports a planned orderly national program for conversion to the metric system and will cooperate with other technical societies and organizations in implementing this voluntary conversion. The Association will use the International System of Units (SI) as modified by the Secretary of Commerce for use in the United States in all official publications, papers and documents. U.S. customary units can be presented in parentheses following the appropriate SI unit, when it is necessary for clarity.
