There are few details to wade through.

We calculate motion shutter speed as Frame Rate * Shutter Angle.

The shutter angle is what we do not have, well not really, on digital cameras.

Watch this video:





The "choppy look" comes from the shutter angle. So for slowmo choppiness you want 60fps * (90/360 shutter angle) = 1/240. This technique is used quite a bit especially when you want to capture pieces of dust particle from an explosion, like in Saving Private Ryan and The Hurt Locker -- among dozens and dozens of other films.

Additionally, its worth mentioning, that you can add the motion blur in post, but you cannot take it away.

And also the feeling this creates is of a heightened reality: things are moving slowly and we are able to see each frame, each spec of dirt passing by. If your story does that, then it's a good time to use the technique. OTOH, the opposite happens to: if the reality is confused, you may want to use an obtuse shutter angle, such as 270-degrees, or 24fps * 270/360 = 1/32 shutter speed. Together with some lens whacking, you will create a drugged-out or punch drunk experience.
