hPa
atm
40 hPa = 0.039477 atm
Full precision:0.039477 atm
Step-by-Step Solution
To convert 40 hectopascals to atmospheres, we divide by 1013.25 because one atmosphere equals exactly 1013.25 hectopascals.
1 atmosphere = 1013.25 hectopascals
Since there are 1013.25 hectopascals in every atmosphere, we divide our value by this factor:
40 ÷ 1013.25 = 0.039477 atmospheres
So 40 hectopascals = 0.039477 atmospheres.
Quick check: 0.039477 × 1013.25 = 40 hectopascals
