Pressure Setting value

[epareja]

Hello,

I´m trying to write the pressure setting value in mm HG, but I didn´t find the conversion factor.

Thanks

I´m trying to write the pressure setting value in mm HG, but I didn´t find the conversion factor.

Since the standard presure of 29.92" is equivalent to 1013.2 mb (or hPA), 1" Hg = 1013.2/29.92 mb.

There are 25.4 mm in one inch, so 1mm = 1013.2 / (29.92 * 25.4)

or 1.333214 mb. If you are writing to FS through FSUIPC you provide 1/16ths of a mb, so multiply your mm by 1.33124 * 16, or 21.33.

Regards,

Pete
