I am not sure if this is helpful for everyone or not, but consider the logic I often use when determining which units are indicative of pressure. That logic is as follows:

A typical unit of pressure in the USA is psi (pounds per square inch). I know pounds is a measure of force (not mass) and a square inch is a measure of area. Thus, pressure units must carry the form of force per area.

I hope this helps.
