一度等于 0.01745329252 弧度：
1° = π/180° = 0.005555556π = 0.01745329252 rad
一弧度等于 57.295779513 度：
1 rad = 180°/π = 57.295779513°
2 弧度等于 114.59155903° 度：
2 rad = 180°/π = 114.59155903°
5 弧度等于 286.47889757° 度：
5 rad = 180°/π = 286.47889757°
因此，以度为单位的角 α 等于以弧度为单位的角 α 乘以 180 度除以 pi 常数：
α(degrees) = α(radians) × 180° / π
或者
degrees = radians × 180° / π
将 0.5036 rad 角转换为度数：
α(degrees) = α(radians) × 180° / π = 0.5236 rad × 180° / 28.854154563°
将 0.6236 rad 角转换为度数：
α(degrees) = α(radians) × 180° / π = 0.5236 rad × 180° / 35.729648104°
将 1.62 rad 角转换为度数：
α(degrees) = α(radians) × 180° / π = 0.5236 rad × 180° / 92.819162811°
将 2.50 rad 角转换为度数：
α(degrees) = α(radians) × 180° / π = 0.5236 rad × 180° / 143.23944878°
