Additional Informations

Angular Units

  • Degree (°):This is the fundamental unit for angular measurement. All other units are defined relative to one degree.
  • Radian:Defined as π/180 radians per degree, 1° is approximately 0.017453292519943 radians. Radians are extensively used in mathematics, physics, trigonometry, and calculus.
  • Grad (Gradian) / Gon:Since a full circle is 400 gradians, 1° is roughly 1.1111111111111 gradians. This unit is popular in engineering and surveying.
  • Minute (Arcminute):One degree is divided into 60 arcminutes, providing a finer subdivision for precise measurements.
  • Second (Arcsecond):Each arcminute contains 60 arcseconds, so 1° equals 3600 arcseconds.
  • Sign:In astrology, the zodiac is divided into 12 signs of 30° each, meaning 1° is equivalent to 1/30 (≈0.033333333333333) of a sign.
  • Mil:Often used in military and engineering applications, where a full circle is divided into 6400 mils1° is approximately 17.777777777778 mils.
  • Revolution / Circle / Turn: A complete rotation is 360°, so 1° equals 1/360 (≈0.0027777777778) of a revolution.
  • Quadrant / Right Angle: A quadrant (or right angle) measures 90°, making 1° equal to 1/90 (≈0.0111111111111) of a quadrant.
  • Sextant: Defined such that 1 sextant equals 60°1° represents about 1/60 (≈0.0166666666667) of a sextant.
