Pa to atm converter
1 Pa = 9.86923 × 10-6 atm
And 1 atm = 101,325 Pa. Pascal to standard atmosphere.
Formula
atm = Pa × 9.86923 × 10^-6
A reading of 15 Pa is 15 × 9.86923 × 10^-6 = 0.000148038 atm.

About these units
Pa (pascal): The SI unit of pressure: one newton per square metre.
atm (standard atmosphere): Defined as 101,325 Pa, roughly sea-level air pressure.
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
