There are different ways of measuring angles.
You can convert the measurement of an angle in one unit to another unit by clicking Utilities and then Conversions.
Holding the Control key and typing q has the same result.
In the Conversions window select Angle
Click the unit you have in the Units From: box, and the units you want in the Units To: box.
Enter the number in the lower left box and click Convert.
Above shows 1 degree is 60 minutes.
The conversions are based on:
1 revolution = 360° (degrees)
1° = 60' (minutes)
1' = 60" (seconds)
1 revolution = 2 
radians
1000 mils = 1 radian
(mils for measuring angles are not the same as the mils used for measuring distance)
