3 days ago · To calculate the air pressure at a certain altitude, use this simple formula: P = P0 × exp(-g × M × (h - h0)/(R × T) where: P0 and h0 — The pressure and altitude of the reference point. Often, these values correspond to the ones at sea level. P — The pressure at altitude h. T — The temperature at altitude h.

The formulas used by this elevation, station pressure and sea level pressure calculator to determine each individual parameter are: HP = ((((P / P0) –βb · R / g – 1) / βb) * Tb) + Hb P = P0 · (1 + (βb · (HP – Hb) / Tb))-g / (βb· R) P0 = P / (1 + (βb · (HP – Hb) / Tb))-g / (βb· R)
This is the absolute pressure of air measured at the station. It can be used to set an altimeter so that the altitude reads zero when on the ground at the stations location, and shows the altitude above ground during flight within the vicinity of the station. QFE is a radio operator query code for ‘Field Elevation’ pressure.
This is the absolute pressure of air at sea level, which is derived from reducing the station pressure to the equivalent pressure at sea level using the icao standard atmosphere model formula. This is also called the ‘Altimeter Setting’ because this is often the pressure reading that an altimeter is set to when landing or taking off from a runway l...

Enter the sea level pressure in mmHg (default: 760), the temperature in Celsius (default: 15), and the altitude above sea level in meters (default: 100). The calculator will use the barometric formula to calculate the corresponding altitude pressure in mmHg.
The formulas used by this us standard atmosphere altitude and air pressure calculator to determine each individual parameter are: For L b ≠ 0: P = P b · (T b / (T b + (L b · (H – H b )))) (g · M) / (R* · Lb) H = ( ( (T b / (P / P b) (R* · Lb) / (g · M)) – T b) / L b) + H b. For L b = 0. P = P b · e -g · M · (H – Hb) / (R* · Tb)
