How to calculate the altitude from the pressure sensor data?

[elrhoul]

can you please explain how to get altitude measurement from pressure data from the sensor

[Stan]

The formula that you provided will give the different results to the one in the cited eurocontrol document.

Also the another question arises. The sensor is used for Altitude estimation and that estimation is as a result is used as a proof of beating the record (WORLD RECORD)

The equation to convert barometric pressure to altitude, derived from the first principles, is as shown below.

this should work well for relative altitude measurements. you need to know the current environmental lapse rate. the equation assumes the atmosphere to have a constant lapse rate.
