IS there a formula for atmospheric pressure based on height? Should I have posted this in another section?

Has this ever resulted in confusing situations? Someone taking the "specific gas constant" for one system as being really a constant and applying it to another system?

The formula for atmospheric pressure is P = ρgh, where P is pressure, ρ is density, g is acceleration due to gravity, and h is height.
Atmospheric pressure is typically measured using a barometer, which measures the amount of force exerted by the air on the surface of the liquid in the barometer.
Atmospheric pressure is affected by altitude, temperature, and the amount of water vapor in the air. As altitude increases, atmospheric pressure decreases. As temperature increases, atmospheric pressure decreases. And as the amount of water vapor in the air increases, atmospheric pressure increases.
Changes in atmospheric pressure can indicate changes in weather patterns. High pressure systems are typically associated with clear and calm weather, while low pressure systems can bring about storms and other inclement weather.
No, atmospheric pressure varies depending on altitude and weather patterns. For example, atmospheric pressure is lower at higher altitudes and can also vary due to differences in temperature and humidity.
