Pascal (Pa)
The pascal is the SI unit of pressure and equals one newton per square meter.
History: the pascal is named after Blaise Pascal and is the SI unit of pressure.
Quickly convert pascals to atmospheres without lookup tables or manual math.
This page is focused on converting pascals to atmospheres. Type a number into the first field and the result appears immediately in the second field.
Example: 1 Pa = 0.0000098692 atm. Conversion formula: result = value × 1 / 101325.
Use this converter for everyday calculations, study notes, engineering checks, and quick value verification without installing a separate app.
