Air Pressure at Altitude Calculator

How to use the Air Pressure at Altitude Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

pressure=pressure0 × exp(constant×height/(temperature+273.15))

Interpreting your results

Once you’ve submitted your data, the calculator will output the air pressure corresponding to the entered altitude. Here’s how to interpret the results:

• Air Pressure Output: The result will typically be shown in kilopascals (kPa) or millimeters of mercury (mmHg). Understanding these units is essential as they measure atmospheric pressure. For example, a result of 81.6 kPa indicates that the pressure is significantly lower than sea level pressure.
• Common Mistakes:
  • Entering Incorrect Units: Ensure you consistently use meters or feet. Switching between units without conversion can lead to inaccurate results.
  • Ignoring Altitude Relevance: Remember, elevations over 2,500 meters can drastically alter pressure readings. Always consider the context of your altitude entries.
