Dear Michael,
IEEE/ASTM SI 10 3.3.3.1 states (in part):
[T]he millibar (100 Pa) should be called by its SI name,
the hectopascal (hPa).
I'm sure that you can look up a similar statement in NIST SP 811, freely
available for downloading.

I'm trying to get my company to replace millibar with hectopascal in company
manuals and was looking for an authoritative source that states this. Anyone
have an idea? I was under the impression that millibar was depreciated. In my
travels as a pilot worldwide it seems the pressure stated most outside north
America is hectopascals for atmospheric pressure, mainly because it's the same
as a millibar.
I do have http://www.unitconversion.org/pressure/bar-conversion.html, but would
prefer a website with more authority, a government or educational website would
be best.. Wikipedia does not seem to have this included, with good sources I'd
include it.
