MySQL DEGREES() Function

The DEGREES() function in MySQL converts an angle from radians to degrees. This is a fundamental mathematical function used in trigonometry and other calculations involving angles.

DEGREES(): Definition and Usage

Radians and degrees are two different units for measuring angles. Radians are based on the radius of a circle (2π radians equals 360 degrees), while degrees divide a circle into 360 equal parts. The DEGREES() function is essential for converting results from calculations (or data stored in your database) that use radians into the more familiar degree format.

Syntax

For converting degrees to radians, see the RADIANS() function. The PI() function returns 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);
