Having worked with toe and alignment equipment for longer than I care to
admit. The alignment machines use a "Reference Diameter" to express toe in
inches. The diameter is something like 27.75 inches - the equivalent of
the tire diameter of the tires used by the majority of the vehicles (large
land yachts) of the 50s and 60s.
Toe can be either per wheel or total toe.
A rule of thumb is for toe is: toe in degrees is twice the toe in inches.
