However, in some occasions, it can be measured in radian (rad ^c) or gradian (grad or ^g) units. Below is the conversion of these angle measures in respect to a full rotation in a circle: degree ↔ radian 360° = 6.28 rad degree ↔ gradian 360° = 400 grad radian ↔ gradian 6. ...

If the angle is θ, then this is θ/2π the fraction of the full angle for a circle. So the area of the sector is this fraction multiplied by the total area of the circle or ( θ /2π) x (π R2) = θR2 /2 with θ in radians.
