Hi Frank: The reason I suggested inches for the optical resolution table was that all of the metals that we use for gnomons such as rods, spheres, plates, and cables are sold in inches or fractions thereof, in the US anyway. I agree that most people who have to do math would prefer to use metric, myself included, but we're stuck with the old outdated system and have to live with it.
