Instructions for Utilizing the Calculator

To effectively use the Station Pressure Calculator, follow these steps:

• Altitude: Input the altitude of the location in meters. Altitude represents the vertical distance above sea level and is essential for accurate pressure calculations.
• Temperature: Enter the temperature in Celsius for the given location. Temperature affects air density and plays a role in pressure calculations.
• Humidity: Provide the humidity as a percentage. Humidity is a measure of the moisture content in the air and influences the vapor pressure in pressure calculations.
• Elevation: Input the elevation of the location in meters. Elevation refers to the height of the location above or below a reference point and impacts pressure calculations.
• Dew Point: Enter the dew point temperature in Celsius. The dew point is the temperature at which air becomes saturated, leading to condensation. It influences vapor pressure calculations.
• Wind Speed: Input the wind speed in kilometers per hour. Wind speed affects pressure calculations due to its impact on air movement.
