Dear John, Broadly, I would use the same training techniques used in "Metrication in a day". See http://metricationmatters.com/docs/MetricationInADay.pdf However the "Metrication in a minute component would need to be expanded to include: 1000 micrometre = 1 millimetre and (? if you go to this level) 1000 nanometres == 1 micrometre Note that in saying this I am advocating direct metrication rather than metrication via metric conversion (even in the form of a dual ruler). One of the trainers I worked with in the metal fabrication trade in the 1970s used the line "Don't duel with dual!" to great effect.
