In other words, measure the angle and be content with it.

Measure in degrees, as the equipment does in the tire shop, and forget
inches.

If you really have to one could calculate the degrees from inches and visa
versa, but you need to know the diameter of the rim and you need a sine
table from high school days or, if you can work them, an appropriate
calculator as needed in high school these days:

"Find the sine of the angle from the toe required per side/wheel
(inches) divided by the diameter of the wheel rim (inches)

For example 1/16th inch total "toe-in" which is 1/32" per side = 0.03125"

Assuming a rim diameter of 15" (Taken from the internet).

Toe angle per side is sine of 0.003125/15 = 0.002083 equivalent to
0.119366 degrees which is also 7.16 minutes.

Total toe-in is double the per side toe-in, in this case 14.32 minutes".

Cheers,
