SQL Server DEGREES() Function

The DEGREES() function in SQL Server converts an angle measured in radians to its equivalent in degrees. This is a fundamental trigonometric function used for converting between different angular units.

DEGREES(): Definition and Usage

Radians and degrees are two common units for measuring angles. Radians are based on the radius of a circle, while degrees are based on dividing a circle into 360 parts. DEGREES() is essential for converting calculations or data that uses radians into the more commonly understood degree format.

Related Functions

The RADIANS() function performs the inverse conversion (degrees to radians), and the PI() function provides the value of pi (π), which is frequently used in trigonometric calculations.

Examples

Converting Radians to Degrees

This example converts 1.5 radians to degrees.

SELECT DEGREES(1.5);

Converting 2π Radians to Degrees

Converting 2π radians (a full circle) to degrees should result in 360.

SELECT DEGREES(PI() * 2);
