Yes, atmospheric pressure is roughly 1 bar. My weather station software quotes pressures in mb (millibars) with figures that range from about 970 to
1050 mb. The gauge can changed to display hPa (hectopascals) which are numerically identical (1 mb = 1 hPa), kPa (figures range from 97 to 105) or inHg (figures ranging from 28 to 31.5). Surprisingly it doesn't offer mmHg. I believe that the standard for international aviation is inHg (because it was influenced by the Americans); similarly aviation altitudes are expressed in feet, though I have heard a pilot announce to his passengers that we would be flying at 5000 metres - this was in an internal short-hop flight from Amsterdam (NL) to Paderborn (DE).
