   Normally, _mass_ is what is measured, not weight (force of gravity,
which depends too much on the environment).

   Or any car mechanic with a torque wrench and a metric service manual. 
(Although one written in the US might have goofy values, blindly
converted from foot-pounds.)

   And "Newton" is the man; "newton" is the unit of force.

   My high-school physics teacher drew a healthy-looking stick-figure
horse(?) on the blackboard, and labeled it "cm".  Next to it, he drew a
similarly shaped animal, but on its back, with limp legs, and X's for
eyes, and labeled it "erg".

   No, they use the magnitude of the charge on an electron, just as they
did before the positron was discovered.

   Note: "eV", not "pV".  There is no "e" in "positron".

   Not really.  There's an Engineer Guy movie about the Dvorak keyboard,
by the way:

   Note that SI _did_ take over the world.  (Almost completely.)
