What is Barometric Pressure?
Barometric pressure, also known as atmospheric pressure, is the force exerted by the weight of air in the atmosphere of Earth. This pressure varies with altitude and temperature, decreasing as you go higher above sea level. Understanding barometric pressure is crucial for weather forecasting, aviation, and various scientific applications. At sea level, the standard atmospheric pressure is approximately 1013.25 hectopascals (hPa) or 29.92 inches of mercury (inHg).
How to Use the Barometric Pressure Calculator
Step 1: Enter the altitude value in either meters or feet by selecting the appropriate unit from the dropdown menu. This represents the height above sea level for which you want to calculate the pressure.
Step 2: Input the temperature at the location, choosing either Celsius or Fahrenheit from the unit selector. Temperature affects air density and thus impacts the pressure calculation.
Step 3: Click the calculate button to obtain the atmospheric pressure results.
Step 4: Review the results displayed in both hectopascals (hPa) and inches of mercury (inHg). The calculator also provides a detailed explanation of how the result was obtained using the barometric formula.
Step 5: For different locations or conditions, simply adjust the input values and calculate again. The calculator automatically updates the results based on your new inputs.
Step 6: Check the explanation section below the results to understand the mathematical relationship between altitude, temperature, and pressure in the calculation.
