Iontráil uillinn i gcéimeanna agus brúigh an cnaipe Tiontaigh (m.sh .: 30 °, -60 °):
Tiontaire raidianacha go céimeanna ►
Tá raidian pi cothrom le 180 céim:
π rad = 180 °
Is ionann céim amháin agus 0.01745329252 raidian:
1 ° = π / 180 ° = 0.005555556π = 0.01745329252 rad
Tá an uillinn α i raidianacha cothrom leis an uillinn α i gcéimeanna uaireanta tairiseach pi arna roinnt ar 180 céim:
α (raidianacha) = α (céimeanna) × π / 180 °
nó
raidianacha = céimeanna × π / 180 °
Tiontaigh uillinn 30 céim go raidianacha:
α (raidianaigh) = α (céimeanna) × π / 180 ° = 30 ° × 3.14159 / 180 ° = 0.5236 rad
