This article is about the unit of pressure. For other uses see Pascal (disambiguation)

The pascal (symbol Pa) is the SI unit of pressure. It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, a French mathematician, physicist and philosopher.

Since 1 Pa is a small pressure, the unit hectopascal (symbol hPa) is more widely used, especially in meteorology. The unit kilopascal (symbol kPa) is also in common use.

1 hectopascal = 100 pascal = 1 millibar.
1 kilopascal = 1000 pascal
