I agree with Jim F's comments, but I would like to make an additional point. NIST was the technical advisor (and possibly ghostwriter) for the FTC's detailed rules in support of the FPLA, and advisor to NCWM on the language of the UPLR. As a matter of state and Federal law, the centimeter is an approved unit of length in that legislation (in the range 1.00 - 999 cm). So their position seems pretty clear and happens to be different from yours. (In squared and cubed form, also permitted for area and volume within applicable ranges). Current laws would require amendment to say it can't be used for trade.

Or not use of centimeter. I want everyone to stop using centimeter. How are we to convert to SI if, when we hear centimeter we think, "now how many inches is that"? Centimeter causes this problem because it is near the size of the inch. This makes it hard to stop using inches. People keep comparing centimeters to inches. Millimeter does not have this problem. Can NIST help get rid of inches? Thanks for your ideas. Robert Bushnell, PhD PE member USMA member ASTM
