Another example, which I thought about during my hydrology class, is storm sewer drainpipes. I think the correct solution for that is to designate one pipe company (there are few) to make only Renard number sized pipes in metric, require all new pipe runs to be done in such sizes, and let the other companies metricate when they decide to. Existing pipe runs may be repaired with inch-sized pipes. Pierre
