Also covered are national and international organizations active in the field of standards of measure and commercial standards.
Title Measuring Systems and Standards Organizations, the new publication is designed to further better understanding of past and present measuring systems, and to determine immediate and long-range effects of the use of SI units of measure by industry. Included are chapters, vividly illustrated in color, on the relationship of measuring systems to civilized society, the evolution of the metric system, Britain and the metric system, measuring systems in the United States, the new International System of Units (SI), and the status of commercial and industrial standards.

Copies of Measuring Systems and Standards Organizations are available from the American National Standards Institute at $1.25 a copy. Quantity prices will be provided on request.
