 Ecowitt rolled out a new firmware update in 2025 that dynamically calculates SLP (sea level pressure) factoring in elevation, station pressure,temperature and humidity. This new update is a radical departure from the previous algorithm, where sea level pressures were somewhat crudely approximated using a simple fixed offset.

 QFE calculator: This calculator uses the term QFE instead of station pressure. QFE is the aviation equivalent to station pressure. Click on the QFE button to start and enter in your elevation and sea level pressure/QNH.

 Note: For North America and jurisdictions that use altimeter setting instead of QNH, put the altimeter setting value of your airport into the QNH input box of the the calculator.
