The Excel DEGREES function converts angles (expressed in radians) to degrees. For example, the formula =DEGREES(PI()) returns 180.
Converts radians to degrees
angle - Angle in radians that you want to convert to degrees.
The DEGREES function takes an angle in radians and converts it to degrees.
Converting degrees to radians
Because Pi = 180°, you can use the general formula degrees * PI()/180 to get radians. 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:
