The radian - a unit of angle measure - angular velocity

Sponsored Links

The radian is the SI derived unit of angle.

There are 2 π (pi) radians (about 6.283185) in a complete circle.

  • 1 rad = 360o / 2 π =~ 57.29578o         (1)

The radian is defined as the angle subtended at the center of a circle by an arc of circumference equal in length to the radius of the circle.
