A conversão é feita da seguinte forma:

180º.......................π rad
360º.......................x rad

x . 180º  =  360º . π rad

x = (360º . π rad) : (180º)

x = 2 π rad

Nota:  ≡  →  equivalente

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

A) 60º ≡ π/3 rad

180º......................π rad
60º........................x rad

x = 60 π / 180 

x = π/3 rad

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

B) (de forma análoga ao anterior)

210º ≡  7π/6 r

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

C) idem

150º ≡ 5π/6 rad

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

D) idem

315 ≡ 7π/4 rad 

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

E) idem

45º ≡ π/4 rad 

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

F) idem

300º ≡ 5π/3 rad

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

G) idem

330º ≡ 11π/6 rad

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

H) idem 

90º ≡ π/2 rad

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

I) idem

270º ≡ 3π/2 rad

-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-

J) idem

15º ≡ π/12 rad
