Conversion Factor
1 Pa = 0.00000986923 atm
Reverse Factor
1 atm = 101325 Pa
Worked Example
Convert 25 Pascals to Atmospheres: 25 Pa = 0.000246731 atm
About Pascal (Pa)
The SI derived unit of pressure equal to one newton per square meter (N/m²). Named for 17th-century French mathematician Blaise Pascal, whose work on fluid statics underpins modern pressure theory. The pascal is a small unit — atmospheric pressure is ~101,325 Pa — so engineering and meteorology usually work in kPa, MPa, or hPa. The pascal is the universal SI reference for pressure, used in scientific publication, thermodynamic state tables, and international engineering standards.
About Atmosphere (atm)
A non-SI unit of pressure defined as 101,325 pascals exactly, corresponding to standard sea-level atmospheric pressure. Atmospheres are widely used in chemistry (reaction pressures), diving (depth in multiples of atmospheric pressure), and pressure-sensitive materials research. 1 atm = 1.01325 bar and is slightly different from the "technical atmosphere" (at, 98,066.5 Pa) used in some legacy European engineering — a known source of confusion in older textbooks.

Understanding Pascals
The Pascal (symbol: Pa) is a unit of pressure. The SI derived unit of pressure equal to one newton per square meter (N/m²). Named for 17th-century French mathematician Blaise Pascal, whose work on fluid statics underpins modern pressure theory. The pascal is a small unit — atmospheric pressure is ~101,325 Pa — so engineering and meteorology usually work in kPa, MPa, or hPa. The pascal is the universal SI reference for pressure, used in scientific publication, thermodynamic state tables, and international engineering standards.
It belongs to the metric measurement system.
Pascals are commonly used in tire inflation, weather reporting, scuba diving, and engineering.
Understanding Atmospheres
The Atmosphere (symbol: atm) is a unit of pressure. A non-SI unit of pressure defined as 101,325 pascals exactly, corresponding to standard sea-level atmospheric pressure. Atmospheres are widely used in chemistry (reaction pressures), diving (depth in multiples of atmospheric pressure), and pressure-sensitive materials research. 1 atm = 1.01325 bar and is slightly different from the "technical atmosphere" (at, 98,066.5 Pa) used in some legacy European engineering — a known source of confusion in older textbooks.
Atmospheres are commonly used in tire inflation, weather reporting, scuba diving, and engineering.
Why Convert Pascals to Atmospheres?
Engineers, mechanics, and scientists frequently need to convert pressure between Pascals and Atmospheres when working with different measurement standards. Tire pressure, blood pressure readings, weather barometric measurements, and industrial process specifications may all use different pressure units depending on the region or discipline. Reliable conversion prevents equipment misuse and ensures safety.
Frequently Asked Questions
How do I convert Pascals to Atmospheres?
The SI derived unit of pressure equal to one newton per square meter (N/m²). To convert Pascals to Atmospheres, multiply by 9.8692e-6. For example, 25 Pa equals 0.000246731 atm.
How many Atmospheres are in 1 Pascal?
There are 0.00000986923 Atmospheres in 1 Pascal.
How many Pascals are in 1 Atmosphere?
There are 101325 Pascals in 1 Atmosphere.
What is the formula for Pascal to Atmosphere conversion?
The formula is: multiply by 9.8692e-6. This means 1 Pa = 0.00000986923 atm.
Is a Pascal bigger than a Atmosphere?
Yes. One Pascal is larger than one Atmosphere because 1 Pa equals 0.00000986923 atm, which is less than 1.
When do you need to convert between Pascals and Atmospheres?
A non-SI unit of pressure defined as 101,325 pascals exactly, corresponding to standard sea-level atmospheric pressure. Pascal and Atmosphere are both pressure units, so conversion comes up whenever one source of information uses one unit and another uses the other — a classic cross-reference challenge in engineering, trade, travel, and everyday life.
