Jon I appreciate your patience ! I have been wrapping my head around this and now understand my confusion. So to restate the (now apparent) obvious:
There are 'degrees' of 360' as in circle and then there are 'degrees' as of decimal point....so thought I would document for others (like me), who may come across this at an alignment shop.

Easy solution is at:

For those who enjoy math:
How to convert decimal degrees to degrees,minutes,seconds

One degree (°) is equal to 60 minutes (') and equal to 3600 seconds ("):
1° = 60' = 3600"

The integer degrees (d) are equal to the integer part of the decimal degrees (dd):
d = integer(dd)

The minutes (m) are equal to the integer part of the decimal degrees (dd) minus integer degrees (d) times 60:
m = integer((dd - d) × 60)

The seconds (s) are equal to the decimal degrees (dd) minus integer degrees (d) minus minutes (m) divided by 60 times 3600:
s = (dd - d - m/60) × 3600

Example: Convert 30.263888889° angle to degrees,minutes,seconds:
d = integer(30.263888889°) = 30°
m = integer((dd - d) × 60) = 15'
s = (dd - d - m/60) × 3600 = 50"
So
30.263888889° = 30° 15' 50"
