A **degree** (in full, a **degree of arc**, **arc degree**, or **arcdegree**), usually denoted by **°** (the

It is not an ^{[4]} Because a full rotation equals 2π radians, one degree is equivalent to π/180 radians.

The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year.^{[5]} Ancient

Another theory is that the Babylonians subdivided the circle using the angle of an ^{[6]}^{[7]} The

^{[8]}^{[9]} ^{[10]}

The division of the circle into 360 parts also occurred in ancient ^{[11]}

Twelve spokes, one wheel, navels three.

Who can comprehend this?

three hundred and sixty like pegs.

They shake not in the least.—Dirghatamas , Rigveda 1.164.48

Another motivation for choosing the number 360 may have been that it is ^{[note 1]} making it one of only 7 numbers such that no number less than twice as much has more divisors (sequence A072938 in the ^{[12]}^{[13]} Furthermore, it is divisible by every number from 1 to 10 except 7.^{[note 2]} This property has many useful applications, such as dividing the world into 24

Finally, it may be the case that more than one of these factors has come into play. According to that theory, the number is approximately 365 because of the apparent movement of the sun against the celestial sphere and that it was rounded to 360 for some of the mathematical reasons cited above.
