Lol, I assure you nothing would ruin my holga experience more than exactness would! This is purely a minor curiosity for me.According to the Holga Manual the cloudy setting is equivalent to f8 and the sunny setting is equivalent to f11.
The shutter speed, based on the manual, is 1/100 seconds.
This is for the Holga 120n.
However, based on the rather relaxed build quality of this camera you may in fact get aperture settings as tight as f/20 or as loose as f/5.6. Likewise the shutter speed may have a certain amount of variation.
If you are truly worried about achieving exact exposures you may not be using the proper camera.![]()
And the actual aperture numbers and shutter speed don't matter to me at all. Just the process of selecting an aperture. To cover or to show. That is all. Not a big deal at all. I just have a lot of free time right now so I thought I'd throw it out there.

Thanks for all the answers/opinions and even for the random numbers people seem to love throwing around!
