WebNov 7, 2014 · Nov 7, 2014. Since. 180∘ = π radians, if you want to convert x degrees to radians, then. x × π 180 radians, and if you want to convert x radians to degrees, then. x × 180 π degrees. I hope that this was helpful. Answer link. WebThe radian formula can be written as, 2π Radians = 360° From this, 1 Radian = 360°/2π (or) 1 Radian = 180°/π. Thus, to convert radians to degrees, we multiply the angle by 180°/π. Examples of Converting Radians to Degrees: π/2 = π/2 × 180°/π = 90° π/4 = π/4 × 180°/π = 45° 7π/6 = 7π/6 × 180°/π = 210° 2 rad = 2 × 180°/π ≈ 114.59°
