+# Math::RAD_TO_DEG
+
+```cpp
+constexpr float RAD_TO_DEG = 180.0f / Math::PI;
+```
+
+`RAD_TO_DEG` 是弧度转角度的转换系数。1 弧度等于 `180 / PI` 度，约等于 57.29577951308232087685。使用该常量将弧度值乘以 `RAD_TO_DEG` 即可得到对应的角度值。
+
+**示例：**
+
+```cpp
+#include <XCEngine/Math/Math.h>
+
+float radians = Math::HALF_PI;
+float degrees = radians * Math::RAD_TO_DEG;
+```
