…centibar. The unit of measurement called standard atmosphere (atm) is defined as 101325 Pa, or 101.325 kPa. Meteorological observations typically report atmospheric pressure in hectopascals per the recommendation of the World Meteorological Organization, thus a standard atmosphere or typical sea-level air pressure is about…
