We should remember that the phonograph record has been completely supplanted by the compact disc, which is made to a hard metric standard (15 mm hole, 80 or 120 mm diameter).
Undoubtedly someone out there will know of an obscure person or company still making records ...

Steps in inrement of 1/8th inch is a unit that was called SOOT, in India, and used where 'inches prevail'. Yes, much depend on industrial houses to accept promotion of the METRIC usage.
