Yes, the correct symbol (lower case except for proper-name units) is required of FDA-regulated products. See item 4B, Symbols, at
http://www.fda.gov/ICECI/ComplianceManuals/CompliancePolicyGuidanceManual/ucm073844.htm I can testify to this on the prescription drug side, because I personally see (and, of course, I look for this) manufacturers' drug product labeling using correct symbolism consistently. But I don't know how vigorous the policing of food product is. The Woodbury School article cited below deals with a bag of chips. Individual pharmacy prescription labels are another story. There has not yet been an effort to police what unit symbolism is required by each state on the presciption vials you get from your pharmacist. That is a state function. At the least, it would require some software tweaking.

(pointed) out the misusage of a capital “G” for grams. However, the company informed the boys that the usage was in fact correct through approval from the U.S. Food and Drug Administration. Does anyone know if the US Food & Drug Admin. really sanctions or even requires the incorrect use of the capital "G" for grams, and discourages or perhaps forbids the correct lower case "g"?
