Appendix 1: Conversion Units and Factors

R7 FS (Jan 16, 2005)

Data listed under this heading maybe used as aguide for conversion between the U.S. conventional, U.K.,

and Canadian Imperial units and metric units plus occasionally SI (international system of units) of

measurements. Wherever it is applicable, the units are rounded-offtodigits practical in the roll forming

industry.

Units not used by the industry, for example karat, mile, acre, cm, deciliter,km, and so on, are not listed

in these tables.

Symbols are based on SI units but often comply with former units widely used by the industry. Units

are abbreviated in one or moreways.
