<p>For a mechanical rotary shutter, a shutter angle is the angle of the arc cut into the circular shutter, which is an opening to help "open" the shutter. Then what does a shutter angle correspond to for an electronic shutter which is not a physical circular shutter at all?</p>

It just refers to the shuttet speed and FPS.

As you probably know, 360° means the entire time, the frame is exposed.
0° means it is never exposed, 180° half of the time.

With digital shutters you can just take your FPS, for example 24, and calculate the corresponding value.

For 180°, you can double it 24\*2=48 so youbget a shutter speed of 1/48s.
For 360° you can justvtake the FPS 24FPS = 1/24s.

The formula for any shutter angle being:

FPS / (Shutterangle / 360)
24 / (180 / 360) = 1/48
