Be careful of the source of your station report. In the US, station report pressures related to aviation are in units of "inches mercury" ("Hg) with the preceding 2 or 3 omitted. Here is a resource: https://aviationweather.gov/metar

In the grand scheme of weather, it does not make much difference, as the change in pressure in time or location is more important than the units.
