Question

The air pressure at is almost 15lbs. per square inch [1kg/sq cm].

Answer 1

It seems like your statement is referring to standard atmospheric pressure. At sea level, the average air pressure is indeed about 14.7 pounds per square inch (psi) or approximately 1 kilogram per square centimeter (kg/cm²). This pressure can vary slightly due to weather conditions, altitude, and other factors, but it is commonly rounded to these values in many contexts. If you have a specific location or condition in mind, please provide more details!
