Iontráil uillinn i raidianacha agus brúigh an cnaipe Tiontaigh (m.sh .: 0.5, π / 2, 3π / 2):
Céimeanna go tiontaire raidianacha ►
Tá raidian pi cothrom le 180 céim:
π rad = 180 °
Tá raidian amháin cothrom le 57.295779513 céim:
1 rad = 180 ° / π = 57.295779513 °
Tá an uillinn α i gcéimeanna cothrom leis an uillinn α i raidianacha 180 céim arna roinnt ar tairiseach pi:
α (céimeanna) = α (raidianacha) × 180 ° / π
nó
céimeanna = raidianacha × 180 ° / π
Tiontaigh 2 uillinn raidian go céimeanna:
α (céimeanna) = α (raidianacha) × 180 ° / π = 2 × 180 ° / 3.14159 = 114.592 °
