The 1991 report cites standard atmospheric pressure as 1013.25 mbar or 101.325 hPa or 29.92 inches of mercury.
Why not standardize on the SI conventional kPa way of presenting pressure? For accuracy and precision purposes, it would be 101.325 kPa if decimal points are used or alternatively Pa only as 101 325 Pa with no decimal point.
