I can’t seem to wrap my head around the term pressure.
Vehicle tyres use air pressure, toilets faucets etc use pressure (presumably water pressure),
pressing onto something applies pressure, our blood has pressure, temperature is also affected by “pressure”.
I know there are various types of pressure, and I can’t think of any more examples at the moment, but my point is “pressure” sounds like a very arbitrary or vague umbrella term to me.
Help me make sense of it?

Pressure is the total force in an area divided by the area itself. So you can think of it as the force intensity over a certain area.
If the pressure is 10N/m^2, then that pressure existing on an object with the area of 1m^2 results in that object experiencing 10N of force. Pressure is a useful measure because it normalizes the calculation by area and thus the outcome can be scaled easily.
