Question
I could estimate the area of the thumbnail with the formula of a square like a=a^2 to use as a reference to estimate how many pounds the atmospheric pressure on us equals.
What formulas and theories should I apply to get that pressure in pounds?

Step 1
The formula of pressure is given as,
Force per unit area P=F/A
The SI unit of pressure is Pascal.
1 Pascal is defined as the 1 newton force acting on the unit m2 area.
1 Pa=1 N/m2
The standard unit of pressure is known as atmosphere pressure.
1 atm= 101325 Pa
