Enter the number of pascals that you want to convert to atmospheres.
How to Convert Pascals to Atmospheres
The pascal and atmosphere are both units of pressure. By definition, 1 atmosphere equals exactly 101325 pascals. This means to convert pascals to atmospheres, you divide by 101325.
Formula
Step-by-Step Example
Convert 5 Pa to atmospheres:
We need to convert pascals to atmospheres
Since 1 atm = 101325 Pa, divide by 101325
5 ÷ 101325 = 4.9346163336e-5
5 Pa = 4.9346163336e-5 atm

About These Units
Pascal (Pa)
The Pascal (Pa) is the SI unit of pressure equal to one newton per square meter. Pascals measure atmospheric pressure, sound pressure levels, and material stress. Standard atmospheric pressure is 101,325 Pa. Named after mathematician and physicist Blaise Pascal.
Atmosphere (atm)
One standard atmosphere (atm) equals 101,325 Pascals, 1.01325 bar, or 14.696 PSI—the average air pressure at sea level. Atmospheres measure diving depth (every 10 meters adds ~1 atm), altitude effects, and chemical reactions. Used as a reference pressure in science.
