Now, letâs move on to the atmosphere or atm unit. The standard atmosphere unit is assumed constant. It is equal to the typical air pressure measured at the earth mean sea level. One standard atmosphere or atm is equal to 101,325 pascals or 101.325 kPa or 1,013.35 hPa.
Most National Weather Service measurements are given in inches of mercury. At sea level, standard air pressure is 29.92 inches of mercury and 1,013 millibars. Inches of mercury is measured in how high a column of mercury rises in a barometer.One millibar is equivalent to one-thousandth of a single bar, or 1,000 dynes.
