Yes, indeed. It really seems that avoiding fractions (which inevitably includes not just decimal fractions but also the vulgar fractions like halves, quarters, etc.) is key for real acceptance of the metric system.
Only when a population is already thoroughly versed and comfortable with metric both conceptually and operationally could they conceivably add something like centimeters and use them properly. When it comes to a population that is used to Imperial and needs to switch, whole numbers (and thus millimeters) does seem to be the way to go.

And my mac computer calculator only converts to cm and not mm? ANSWER Because the manufacturers of those items have not yet heard of, less adopted, Pat Naughtin's recommendation. When Pat's recommendation, he has the FACTS that show it works.
