The instruction booklet for your pressure cooker indicates that its highest setting is 12.3 psi? You know that standard atmospheric pressure is 14.7 psi thus the booklet must mean 12.3 psi above atmospheric pressure. At what temperature in degrees Celsius will your food cook in this pressure cooker set on high?
