+
+The **`DEGREES()`** function in SQL is a mathematical function used to convert a value expressed in radians to its equivalent in degrees. This function is available in various SQL dialects, including SQL Server, MySQL, and Oracle.
+
+> **Note:** Functions `RADIANS()` and `PI()` are closely related to `DEGREES()`.
+
+## Syntax
+
+```pseudo
+ DEGREES(number)
+```
+
+**Parameters:**
+
+- `number`: A numeric expression in radians to be converted to degrees.
+
+**Return value:**
+
+Returns the angle in degrees as a numeric value.
+
+## Example 1
+
+This example converts a specific radian value to degrees:
+
+```sql
+Select DEGREES(1.0) as degrees_value;
+```
+
+The output:
+
+| <center>degrees_value</center>     |
+| ---------------------------------- |
+| <center>57.29577951308232</center> |
+
+## Example 2
+
+This query converts PI\*2 radians to degrees:
+
+```sql
+SELECT DEGREES(PI()*2) as degrees_off_of_pi;
+```
+
+The output:
+
+| <center>degrees_off_of_pi</center> |
+| ---------------------------------- |
+| <center>360</center>               |
