The Conversion Formula
To convert pascals to atmospheres, multiply the value by the conversion factor: 1 Pa = 0.00000986923 atm. For a worked example, suppose you need to convert 25 Pa to atmospheres: 25 × 0.00000986923 = 0.000246731 atm. To convert in the opposite direction, divide by 0.00000986923, or equivalently multiply by 101325.
About pascals
The pascal (Pa) is the SI unit of pressure, named after French polymath Blaise Pascal. One pascal is one Newton of force per square meter. It is a very small unit—atmospheric pressure is over 100,000 pascals! Because it's so small, meteorologists and engineers often prefer kilopascals (kPa) or hectopascals (hPa). pascals are commonly used in Scientific research, Acoustics (Sound pressure), Ventilation systems (very low pressure), and Clean room standards, Geophysics.
The pressure of a dollar bill on a table is roughly 1 Pascal.
About atmospheres
The standard atmosphere (atm) represents the average pressure exerted by Earth's atmosphere at sea level. It was originally defined by the height of mercury in a barometer (760 mm). It is the most intuitive unit for understanding pressure: 2 atm means double the pressure you feel standing on the beach. atmospheres are commonly used in Diving depth (1 atm per 10m), Chemistry (Standard Temp/Pressure), Hyperbaric chambers, and Spacecraft engineering, Altitude simulation.
At sea level, the air pressure is exactly 1 atm.
When Would You Convert pascals to atmospheres?
Converting between pascals and atmospheres is one of the most common pressure conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 Pa = 0.00000986923 atm) memorized or bookmarked can save time in professional and everyday contexts alike.
