๐ Standard Benchmark Reference Values
Standard reference atmospheric pressure at sea level.
Exact RatioAbout Standard Atmosphere (atm)
An internationally agreed reference pressure defined as exactly 101,325 pascals (1.01325 bar).
History: Originally established as the pressure exerted by 760 mm of mercury at sea level and 0 ยฐC.
Common Uses: Chemical thermodynamics, underwater diving depths (1 atm per 10m depth), and gas cylinders.
About Pascal (Pa)
The SI coherent derived unit of pressure, equal to one newton per square meter (1 N/mยฒ).
History: Named after French polymath Blaise Pascal; adopted by the 14th CGPM in 1971.
Common Uses: Scientific acoustics, building ventilation pressures, and materials stress modeling.
โ Frequently Asked Questions
How many Pascals are in 1 Standard Atmosphere?
There are exactly 101325 Pascals in 1 Standard Atmosphere (1 atm = 101325 Pa).
What is the formula to convert Standard Atmosphere to Pascal?
The formula is: Pascal = Standard Atmosphere ร 101325. Since 1 Standard Atmosphere = 101325 Pascals, multiply the value in Standard Atmospheres by 101325.
How do I convert 1 atm to Pa manually?
To convert 1 atm to Pa: apply the formula Pascal = Standard Atmosphere ร 101325. Substituting gives: 1 ร 101325 = 101325 Pa.
