Hi, F1, I think you'll find that the reason its expressed as so many
mm, or fractions of an inch, both over about an 18 inch span, is
because the angle is too small, in degrees, to be meaningful, or
measurable with garage equipment.
I spent many years playing with steering systems, of different
types, with different linkages, of different effectiveness between
the wheels. I came to the conclusion that the manufacturers wanted
the minimum toe-in that would prevent the system producing toe-out,
when under moderate braking.
Braking causes the wheels to try to toe-out, & it doesn't take much
wear in multi link systems, to cause rapid wear of the inside of the
tyres, even if the thing measures OK when static. That's why
different systems require different toe-in settings.

PS. If you want the angle, start from a piont, [A], & draw a line 18
inches long. Make the end piont [B]
Measure up, at a right angle, 1/16Th of an inch from [B], & make
point [C].
Draw a line from [A] to [C], & the difference between the 2 lines is
the angle. You will need a sharp pencil, or you won't be able to see
it.
