Pressure Double: Measured pressure in hPa (mBar) at the "From" altitude
FromAltitudeAboveMeanSeaLevel Double: "Altitude at which the input pressure was measured (metres)
ToAltitudeAboveMeanSeaLevel Double: Altitude to which the pressure is to be converted (metres)

Double
Pressure in hPa at the "To" altitude

Uses the equation: p = p0 * (1.0 - 2.25577E-05 h)^5.25588
