Conversion formula

Atmosphere to Hectopascal formula: value in hPa = value in atm × 1013.25.

Hectopascal to Atmosphere formula: value in atm = value in hPa × 0.00098692326671601.

How to convert Atmosphere to Hectopascal

To convert Atmosphere to Hectopascal, multiply the value in atm by 1013.25. This gives the result in hPa.

For example, 1 atm = 1013.25 hPa and 10 atm = 10132.5 hPa.

What is Atmosphere?

Atmosphere (atm): A reference pressure for comparing gas conditions, rather than a reading of today’s weather. 1 atm = 101 325 Pa.

What is Hectopascal?

Hectopascal (hPa): Weather reports use this scale for atmospheric pressure, often around a thousand hectopascals near sea level. 1 hPa = 100 Pa.
