About hPa and pascals

hPa and pascals are common pressure measurements.

💡 Did you know?

1 hPa = 100 Pa. The hectopascal was created because 1 Pa (1 N/m²) is too small a unit for weather (standard pressure is 101,325 Pa = 1013.25 hPa). 1 hPa is exactly equal to 1 mbar (millibar), the older unit still common in older weather records.
