Sign (sign)
A sign is 1/12 of a circle or 30°, corresponding to one zodiac sign. The zodiac divides the ecliptic into 12 equal signs of 30° each. Used in astrology and historical astronomy. The Sun moves through approximately one sign per month.
Radian (rad)
A radian (rad) is the SI unit of angle where the arc length equals the radius. One radian ≈ 57.3°. A full circle is 2π radians (≈6.28 rad). Radians are essential in calculus, physics, and engineering. Trigonometric functions in most programming languages use radians.
