Pat Naughtin has presented extensive arguments recommending that the "centi" submultiples not be used when converting a country from Imperial units to SI. However, the UKMA web site argues the opposite, claiming that the push to use only submultiples separated by a factor of 1000 (10^3) from a base unit, such as millimetres for lengths or distances larger than 1 mm but smaller than 1 m, continues to foster the false impression (at least in the UK) that the SI is "good" only for scientific and engineering disciplines rather than every domain and forces citizens to use unnecessarily large numbers with those subunits -- numbers that are not user friendly and that give a false indication of precision.
I'm curious if anyone associated with the UKMA (Chris? Others?) would care to explain why they have taken that position despite the information provided by Pat Naughtin. (I'm still debating in my own mind which is the better way to go, so I'm very interested in the potential discussion on this topic.)

I have searched the UKMA metric site but I failed to find any statement favoring the centimetre rather than the millimetre, or indeed any statement favoring any particular units. I think that the statement Esra referred to must have been removed from the UKMA web pages because of disagreement among the membership regarding Lady Attlee's position favoring the centimetre.
