Details The unit "second" is not used to measure angles. Instead, it is a unit of time. In the field of angles, the primary unit of measurement is "degrees" (°), followed by "arcminutes" (') and "arcseconds" ('').

An angle of 1 degree can be further divided into 60 arcminutes, and one arcminute can be subdivided into 60 arcseconds. So, for angular measurements, it would be technically called "arcsecond" rather than "second".

For example, an angle might be represented as 30 degrees, 10 arcminutes, and 5 arcseconds, which can be notated as 30° 10' 5''.
