HIDALGO, Luis Guillermo  and  HIDALGO, Jesús Alfonso. QNH reconversion into atmospheric pressure. Rev. Téc. Ing. Univ. Zulia [online]. 2013, vol.36, n.3, pp.240-242. ISSN 0254-0770.

The present technical note embraces calculations to reconvert the aviation QNH into atmospheric pressure with the help of the OACI standard atmosphere formulae and the airport altitude. That reconversion permits the gathering of hourly real time pressure data of unusual acquisition from hourly QNH data easy to obtain by Internet. The pressure data might be used in applications such as the calibration of barometers and the standardization of gaseous volumes.
