Hello How do you convert millimetres to degrees (minutes and seconds), as in wheel alignment. I think that there is a formula for this but cannot for the life of me remember what it is. Could you please help? Thanks

I can help with toe in/toe out.
The circumference of the tire, is the measurement all the way around, a complete circle. Therefore the circumference is equal to 360 degrees.
Therefore: circumference / 360 = millimeter per degree
For example, if the circumference of the tire is 1000 mm, then: 1000/360 =2.77778 There are 2.7778 millimeters per degree
If you only know the diameter or radius of the tire, you can calculate the circumference with one of the following: circumference = Pi * diameter circumference = Pi * 2 * radius
