Questions about the origin of the differential pressure formula?

Isn’t pressure equal to F/S? Why is it mass divided by area here?

This post was last edited by qugd on 2019-10-8 at 13:57. Is there something wrong with this formula? Under Earth’s normal gravity, mass is equivalent to weight, and weight is equivalent to pressure – what’s wrong with that? Understanding the specific meaning of a physical formula does not involve mechanically figuring out what those abbreviated characters represent.
