Appendix 7. Reference List for Metric Measurements

American National Standard for Metric Practice. ANSI/IEEE STD 268-1992. Bethesda, MD: American National Metric Council, 1992.

American Society for Testing and Materials. Standard for Metric Practice. ASTM E380. Philadelphia: ASTM, 1982.

Artusa, Elisa A. SI (Metric) Handbook. National Aeronautics and Space Administration, John F. Kennedy Space Center. NASA TM-109197. Baltimore, MD: NASA Center for AeroSpace Information, 1994.

Provides information for an understanding of SI units, symbols, and prefixes, style and usage in documentation in both the U.S. and in the international business community; conversion techniques; limits, fits, and tolerance data; and drawing and technical writing guidelines. Also provides information on SI usage for specialized applications like data processing and computer programming, science, engineering, and construction. Related information in the appendixes includes legislative documents, historical and biographical data, a list of metric documentation, rules for determining significant digits and rounding, conversion factors, shorthand notation, and a unit index.

Conversion Factors. Northridge, CA: U.S. Metric Association.

A comprehensive one-page table that provides conversion factors from both inch-pound units to metric system units and from metric system units to inch-pound units. Shows the conversion factors for length, area, volume, torque, mass, energy/work, power, pressure/stress, force, speed, and temperature.
