Conversion formula

Forward

atmospheres = pascals × 9.8692e-6

Reverse

pascals = atmospheres × 101,325

Example: 10 Pa × 9.8692e-6 = 9.8692e-5 atm.

About both units

From

Pascal

The pascal is the SI unit of pressure — one newton per square metre. Named after Blaise Pascal. 1 Pa is a very small pressure; atmospheric pressure is about 101,325 Pa. Pressure readings in engineering are usually in kPa or MPa.

Real-world: Atmospheric pressure: 101,325 Pa. Conversation level: 0.001 Pa sound pressure. Truck tyre: 900,000 Pa.

Atmosphere

atm

The standard atmosphere equals 101,325 pascals exactly — defined by CGPM in 1954. Represents average sea-level atmospheric pressure. Used in chemistry, aviation and engineering as a reference pressure.

Real-world: Sea-level pressure: 1 atm. Mount Everest summit: ~0.33 atm. Submarine at 100 m: ~11 atm.

Tips & common mistakes

Quick tips

1 Pa = 1 N/m².
1 kPa = 1000 Pa; 1 MPa = 1,000,000 Pa; 1 bar = 100,000 Pa.
Use kPa, MPa or bar for practical engineering work.

Avoid these

Confusing Pa with psi — 1 psi = 6895 Pa.
Using Pa for tyre pressures — 220,000 Pa unwieldy; use 2.2 bar.
Mixing Pa absolute and Pa gauge without specification.

Frequently asked questions

How many atmospheres in a pascal?

One pascal equals 9.8692e-6 atmospheres.

How do I convert pascals to atmospheres?

Multiply the pascal value by 9.8692e-6 to get the equivalent in atmospheres.
