Measuring toe in is much more fun.

+1 at least

According to this graphic, I need to repeatably measure toe to plus or
minus 2 minutes of accuracy and camber to plus or minus 1 minute of
accuracy:

Static camber will be measured in degrees, so the plus or minus 1 minute of
accuracy is easy enough for me to understand.

But sttic toe is usually measured in inches, so a problem is how do I
convert the 2 minutes of accuracy to a plus or minus inch figure?
