How Many Degrees in a Radian?
クイックアンサー
There are approximately 57.296 degrees in a radian.
1 radian = 180/π ≈ 57.296°
変換の理解
One radian is the angle subtended at the center of a circle by an arc equal in length to the radius. Since a full circle has 360° and 2π radians, one radian equals 360/(2π) = 180/π ≈ 57.2958°. Radians are the natural unit for angles in mathematics and physics.
