In 18015 I relayed the story that metric is so simple that
factory people who can not do fractions can make inch parts
by doing it in millimeters.
The inference is that it is cheaper to do most production with
metric measures even for inch parts. So, we should promote
metric because it is cheaper.
This has no relation to the change to metric in field use of
fittings.
