How to convert hectopascals to atmospheres
atm = hPa × 0.000986923
Multiply the value in hectopascals by 0.000986923. To go the other way, divide by the same number, or multiply by 1,013.25. For example, 5 hPa × 0.000986923 = 0.004935 atm.
About the units
Hectopascals (hPa). 100 pascals, the same as a millibar. Weather maps and forecasts.
Atmospheres (atm). Standard sea-level air pressure, exactly 101,325 pascals.
