Radiyan shi ne na'urar ma'auni . Ana nuna ta ta hanyar alamar "rad" ko, ƙasa da yawa, c (don ma'aunin madauwari). Radian ya kasance ɗayan ƙarin SI, to amma an canza shi zuwa naúrar da aka samu a cikin shekara ta alif Dari Tara da casain da biyar 1995. [1]Tsawon baka na radians yayi daidai da radiyan daga da'irar da yake sashi.[2]
