The RADIANS SQL Function in MySQL and MariaDB - Radians calculation from degrees

RADIANS	Syntax:	RADIANS(Number)
	Return value:	FLOAT
	Function type:	Numeric function

Function Description

The RADIANS() function returns the radians of a unit circle with a perimeter of 2*π (PI) from the degree specification in "Number".

The SIN(), COS(), COT() and TAN() functions require radians as an argument.

Given a degree of 180, the function returns π (PI).

The function returns NULL if the argument is NULL.

RADIANS() is the inverse function of DEGREES()

SQL Examples for the RADIANS function


select radians(45);
select radians(60);
select radians(180);
select radians(360);
select radians(0);

How to use the RADIANS() function in MySQL and MariaDB databases

The RADIANS() function in MySQL and MariaDB is used when angles are in degrees and need to be converted to radians for mathematical calculations, or when working with trigonometric functions that require angles in radians.
