You can express angles in radians, decomal degrees (1.2345 degrees) or in
degrees, minutes, seconds. To keep terminology straight, especially
when the angle
is less than one degree, the term arc minute and arc second is used, so
that it is
not confused with a time measurement.

One degree equals 60 arc minutes, and 3600 arc seconds. So, 1.2345 degrees
is equal to 1 degree, 14 minutes, 4.2 seconds. This can also be written as
1 (degree circle) 14' 4.2"
