Understanding Angle Units

  • Degree (°): A measurement of a plane angle, representing 1/360 of a full rotation.
  • Radian (rad): The standard unit of angular measure, used in many areas of mathematics. 1 rad ≈ 57.296°.
  • Gradian (grad): Also known as gon, representing 1/400 of a full rotation.
  • Turn (tr): A unit of plane angle equal to 360°, 2π rad, or 400 grads.
  • Arcminute ('): 1/60 of a degree.
  • Arcsecond (''): 1/60 of an arcminute.
