don't forget pressure

  mmHg is, due to historical reasons, pretty well distributed, and hPa is also rather widely used. inHg appears to have way less penetration than feets for altitude or feet/minute for vertical speed (way inferior to meter/second IMHO).

    In the US at least, inHg is used to specify the altimeter setting in aviation.

      Unlike exporting feet for altitude, inHg didn't take hold as much from what I've seen.
