Purpose
Return value
Syntax
=DEGREES(angle)- angle - Angle in radians that you want to convert to degrees.
Using the DEGREES function
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:
| Formula | Degrees |
|---|---|
| =2*PI() | 360 |
| =PI() | 180 |
| =90*PI()/180 | 90 |
| =45*PI()/180 | 45 |
| =30*PI()/180 | 30 |
| =20*PI()/180 | 20 |

RADIANS Function
The Excel RADIANS function converts degrees to radians. For example, =RADIANS(180) returns 3.1415 or the value of π (pi)....
PI Function
The Excel PI function returns the value of the geometric constant π (pi). The value represents a half-rotation in the radian angle system. The constant appears in many formulas relating the circle, such as the area of a circle....
