Currently I am on no specific timetable to convert to the metric system. I still can not
think with it, and have to convert in my mind when someone gives me a metric measurement.
Basing subdivisions on 12, mean that 1/2 , 1/3 , 1/4 , 1/6 , 1/12 are natural subdivisions,
giving much more range for trading quantities.
