Convert hectopascals (hPa) to atmospheres (atm) with formulas, examples, and conversion tables.
To convert 1 hectopascals to atmospheres, we divide by 1013.25 because one atmosphere equals exactly 1013.25 hectopascals.
Since there are 1013.25 hectopascals in every atmosphere, we divide our value by this factor:
So 1 hectopascals = 0.000987 atmospheres.
To convert hectopascals to atmospheres, divide the value by 1013.25.
1 atmosphere = 1013.25 hectopascals
