๐ Standard Benchmark Reference Values
Standard reference atmospheric pressure at sea level.
Exact RatioAbout 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.
About 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.
โ Frequently Asked Questions
How many Standard Atmospheres are in 1 Pascal?
There are exactly 0.00001 Standard Atmospheres in 1 Pascal (1 Pa = 0.00001 atm).
What is the formula to convert Pascal to Standard Atmosphere?
The formula is: Standard Atmosphere = Pascal / 101325. Since 1 Standard Atmosphere = 101325 Pascals, divide the value in Pascals by 101325.
How do I convert 1 Pa to atm manually?
To convert 1 Pa to atm: apply the formula Standard Atmosphere = Pascal / 101325. Substituting gives: 1 / 101325 = 9.8692e-6 atm.
