Radians (unitas)

E Vicipaedia
Radians.

Radians (n. -tis),[1] vulgo radian, breviter rad, est unitas mensurae angulorum planorum. In omnibus circulis, angulus unius radiantis arcum secat cuius longitudo par radii circuli est. Quoniam longitudo circuli radii est , angulus plenus (360°) est, atque rad; angulus rectus (quadrans anguli pleni, 90°) rad. Unum radians ergo est ca. 57,3°.
