Sounds interesting, and valuable, although I don't see the connection
with terrorists.

We are having a ball going
through all the catalogs with specifications in both systems trying to match
one to the other. For example a motor for sale boasts 65 Newtons while
another catalog boasts a motor with 10/inch/lbs torque at 180 RPM. I can
visualize ten pounds at the end of a rod attached to the shaft rotating at
180 RPM but damned if I can visualize the Newton thing. So why bother? I'll
go for the inch pound solution since it is visible. Let the rest of the
world wrestle with non-visializable dimensions if they want. Five ft. two
and eyes are blue... how many cms around the waist? and what cup size?

100gm of meat and/or cheese is about right for a sandwich.

A thou is big for precision work, a tenth a bit small, wheras 0.1mm or
0.05mm is about right.

100kg is a big guy, 50kg is a small gal

When I design in Solidworks I key in mm or inches interchangably or
even mixed (0.125" + 0.5mm, for a clearance dimension for example).

It's like you speaking Spanish, I'd imagine, a bit of effort but no
big deal, and you see benefits in the long run for a some work in the
short term. There are lots of people who say scr*w Spanish, let them
speak English if they want to do business, right? ;-)
