Converting alignment toe setting in minutes to inches
 

anyone have a clue?
I am trying to convert .12 minutes of toe to inches.

From Wikipedia:
Angles are considered dimensionless, since they are defined as the ratio of lengths. There are, however, several units used to measure angles.

With the notable exception of the radian, most units of angular measurement are defined such that one full circle (i.e. one revolution) is equal to n units, for some whole number n. For example, in the case of degrees, n = 360. A full circle of n units is obtained by setting k = n/(2π) in the formula above.

The degree, denoted by a small superscript circle (°) is 1/360 of a full circle, so one full circle is 360°. One advantage of this old sexagesimal subunit is that many angles common in simple geometry are measured as a whole number of degrees. (The problem of having all "interesting" angles measured as whole numbers is of course insolvable.) Fractions of a degree may be written in normal decimal notation (e.g. 3.5° for three and a half degrees), but the following sexagesimal subunits of the "degree-minute-second" system are also in use, especially for geographical coordinates and in astronomy and ballistics:
The minute of arc (or MOA, arcminute, or just minute) is 1/60 of a degree. It is denoted by a single prime ( ′ ). For example, 3° 30′ is equal to 3 + 30/60 degrees, or 3.5 degrees.

So .12 Minutes should be = to .12 times (1/60) degrees. Or .002 degrees. If you check the archives I think you can find a Dave Farmer post on how to convert degrees to inches.

i've never heard of toe being measured in minutes.

only degrees and inches.

.1deg=1/32" measured at the rim (more or less). .1deg is about the equivalent of 1 flat (1 turn of a wrench, or 1/6 of a tie rod turn), and is about as precise as you can get in reality.

I bet that should be .12deg, as .002deg is not attainable precision for toe.
