- angle - Angle in radians that you want to convert to degrees.
The DEGREES function takes an angle in radians and converts it to degrees. Radians measure angles using the radius of a circle, as illustrated in this image:
To convert degrees back to radians, you can use the RADIANS function.
Converting degrees to radians manually
Because Pi = 180°, the general formula for degrees to radians is degrees * PI()/180. For example, to convert 45° to radians, the Excel formula would be 45*PI( )/180 which equals 0.7854 radians. More examples in the table below:
