Minutes in decimal degrees

Minutes in decimal degrees
• The wheel alignment values are specified in degrees and minutes in the Technical Manual (division in
60 units)!
• In countries in which the decimal degree is widely used, the electronic wheel alignment testers can be
converted from degrees/minutes (division in 60 units) to decimal degrees (division in 100 units) by
presseing a key (special function)! This function is standard for the electronic wheel alignment testers
approved by Porsche.
Using the conversion table, minutes (') can be converted into decimal degrees and decimal degrees
•
into minutes (')! To do this, read out the required values with the help of the coordinates!
min (') 0
0 0.017
10 0.167 0.183
20 0.333 0.350
30 0.500 0.517
40 0.667 0.683
50 0.833 0.850
60 1.000

Conversion from minutes to decimal degrees (examples)

• Example 1: Toe 17 min (17') = 0.283 decimal degrees according to table. Procedure for this: The
imaginary line starting at the top of the 7 mins column moving downwards and the line starting on the
left in the 10 mins row moving right meet at point/column 0.283.
• Example 2: Camber 1° 25' (1 degree and 25 min) = 1.417 decimal degrees. This is the result from the
table (1 degree or 60 mins) = 1.000 + 0.417 (25 min).

Conversion from decimal degrees to minutes (examples)

• Example 1: Toe 0.350 decimal degree = 21 min (21'). The decimal value (0.350) is searched for in the
table. The coordinates are subsequently formed from this point/value. Line to the left = 20' and line
upwards = 1' (amounts to 20' + 1').
• Example 2: Camber 1.683 decimal degrees = 1° 41' (1 degree and 41 min). This is attained as follows:
Divide the value in 1,000 = 1 degree (1°) and search for the remaining value 0.683 in the table. Then
