  • tasanurga mõõtühik
  • a unit of plane angular measurement that is equal to the angle at the center of a circle subtended by an arc whose length equals the radius or approximately 57.3 degrees
Good to know
  • 1 rad = 57º17 '45", 1º = π/180 (≈ 0,017453) rad.
radiaan
Usage examples
  • Üks radiaan (lüh. rad) on selline kesknurk, mis toetub kaarele, mille pikkus on võrdne selle ringjoone raadiusega. Ühele täisringile vastab pöördenurk 2π rad, seega 1 rad = 360º/2π ≈ 57º.
