Netatmo Weather Map Pressure Indications

Post by RandyBrown » 20 Aug 2017, 23:38

While looking at the settings for the web-based Netatmo Weather map, I see display indications for pressure readings that can be changed between md, inHg, and mmHg. To be honest I have no ideal which is the correct choice for viewing and understanding simple at-a-glance pressure readings.

mb: Meteorologists use a metric unit for pressure called a millibar and the average pressure at sea level is 1013.25 millibars. Terms for using data resources.

inHg: Inch of mercury (inHg and "Hg) is a unit of measurement for pressure. It is still used for barometric pressure in weather reports, refrigeration and aviation in the United States. It is the pressure exerted by a column of mercury of 1 inch (25.4 mm) in height at the standard acceleration of gravity.

mmHg: Although not an SI unit, the millimeter of mercury is still routinely used in medicine, meteorology, aviation, and many other scientific fields. One millimeter of mercury is approximately 1 torr, which is 1/760 of standard atmospheric pressure (101325760 =133.322368421 pascals).

Question: Which of the three is most used by Netatmo users mb, inHg, or mmHg?
