"SI units to be given first, with the corresponding non-SI units following in parentheses" http://www.lbl.gov/Workplace/RPM/R1.23.html "metric units should be used whenever possible with the inch-pound units following in parentheses." http://ts.nist.gov/ts/htdocs/200/202/4855.htm "Neither the amendments to the FPLA nor the Commission's regulations require that the measurement systems be used in a particular order.(19) Thus, manufacturers have discretion to put SI metric units first or customary inch/pound units first as they so choose." http://www.ftc.gov/os/statutes/fpla/basis_jan1994.html As a matter of writing style, why is the FPLA still written using the inch-pound units first when the Federal government agencies all appear to have a 'write metric units first' policy? -- Terry Simpson Human Factors Consultant [EMAIL PROTECTED] www.connected-systems.com Phone: +44 7850 511794
