How to convert pascals to atmospheres

atm = Pa ÷ 101,325

Example: convert 8 pascals to atmospheres.
8 Pa ÷ 101,325 = 0.000078953861 atm

The same relationship in reverse: 1 standard atmosphere = 101,325 pascals, so you can also multiply by 0.000009869233. Need the other direction? Use the atmospheres to pascals converter.

You will typically need this conversion for chemistry and physics problems.

About the units

Pascal (Pa)

The SI unit of pressure: one newton per square meter. A very small unit — atmospheric pressure is about 101,325 Pa.

Standard Atmosphere (atm)

Exactly 101,325 Pa, the average air pressure at sea level. Used in chemistry and diving.

Frequently asked questions

How many atmospheres are in a pascal?

1 pascal = 0.000009869233 atmospheres. Going the other way, 1 standard atmosphere = 101,325 pascals.

How do I convert pascals to atmospheres?

To convert pascals to atmospheres, divide by 101,325. The formula is atm = Pa ÷ 101,325.

What is 8 Pa in atm?

8 pascals is 0.000078953861 atmospheres (8 Pa ÷ 101,325 = 0.000078953861 atm).
