What is the maximum pressure of the pressure cooker?

Pressure p=mg/s 1, where m is the mass of the pressure-limiting valve, and the unit is kg; G=9.8 1, which is the acceleration of gravity; S 1 is the area of the pressure-limiting valve, that is, the area of the pressure-limiting outlet, in cm2. The unit of pressure thus calculated is kg force /cm2, which is about 0.98 1 standard atmospheric pressure.

The force at the interface between the lid and the pot is p*s2, where s2 is the area of the bottom of the pot. At this time, the unit is kg force, and the force (Newton) is multiplied by the acceleration of gravity.
