This document covers a dual dimensioning practice that provides both U.S. customary inch-pound units and SI metric units for all dimensions on the field of the drawing. The scope does not include the various methods by which computer programs are used for dual dimensioning. In one method that has had some usage, drawings are dimensioned in SI (metric) units, with conversions to U.S. customary inch-pound units provided in a computer-generated chart on the drawing.

This SAE Standard provides information on the International System of Units (abbreviated SI in all languages), and its application in measurement unit usage.

The scope of this SAE Technical Standards Board document (TSB) is to provide uniform guidelines for Technical Committees of the SAE Technical Standards Board in the development, preparation, and issuance of technical reports. Adherence to this TSB can expedite the processing of uniform and consistent SAE technical reports, and will facilitate their use and reference by government, industry, and other organizations.

This SAE Standard provides basic information on the International System of Units, abbreviated SI in all languages, and its application in engineering practice and measurement unit usage.

This document covers a dual dimensioning practice that provides both U.S. customary inch-pound units and SI metric units for all dimensions on the field of the drawing. The scope does not include the “chart method”—whereby drawings are dimensioned only in SI units—with conversions to inch-pound units provided in chart form (usually computer-generated) on the drawing. Further information on the chart method is found in SAE Handbook Supplement J1066, “Recommended Guidelines for Company Metrication Programs in the Metalworking Industry.”
