I think it is useful to have actual
instances, in the field, of ease of metric measurement.
We hired a bulldozer operator to
bulldoze and reshape a large seasonal pond on our property. One of the
steps was using a transit to establish the desired water line over rough
terrain. The contractor had a vertical measuring stick marked, of course,
in inches. One of us moved the stick around and one of us sighted
through the transit, and at several times in the process he had to add or
subtract inches mentally ("let's see, that's 17 1/2 inches and 19 1/2, what's
that now...?") I pointed out that with metric usage the task would have
been much simpler.
Of course he wasn't about to change
his measuring stick, but he did pause to think about it.
