How to convert pascals to atmospheres
atmospheres = pascals × 0.0000098692
The pascal — one newton per square meter — is the SI pressure unit, named for Blaise Pascal. It is tiny: atmospheric pressure is about 101,325 Pa.
The standard atmosphere (101,325 Pa) represents average sea-level air pressure — the natural reference for diving depth and chemistry.
