This table is for general use for eruption to 1 atm pressure for. The standard atmosphere value has many uses in atmospheric calculations and one example of this is the FAA procedures for setting aircraft altimeters at altitudes of 18,000 feet and above to ensure all aircraft are using the same pressure reference when measuring the height above sea level. 25 115.6 208.3 28.2 2.91 50 126.5 228.3 48.2 4.97 100 142.8 256.8 76.7 7.91 134. So 1.01325 bar is not a real average as such, but used more as a sensible value that has been chosen as the representative average pressure for the Earth’s atmosphere at sea level. Since the actual pressure at sea level varies in an unpredictable way due to constant changes in weather conditions, an overall true average is not practical to determine or use universally because it would need to be constantly iterated to keep up with climatic variations. 1 pascal is equal to 1.0E-5 bar, or 0.00014503773800722 psig. Task: Convert 75 psi to atmospheres (show work) Formula: psi 14.695948775 atm Calculations: 75 psi 14.695948775 5.103447 atm Result: 75 psi is equal to 5.103447 atm Conversion Table For quick reference purposes, below is a conversion table that you can use to convert from psi to atm.
You can view more details on each measurement unit: bar or psig The SI derived unit for pressure is the pascal. We assume you are converting between bar and pound/square inch gauge.
#48.2 PSI TO ATM HOW TO#
The internationally accepted ‘standard’ value at sea level is 1.01325 bar. How to Convert Psi to Standard Atmosphere. More information from the unit converter How many bar in 1 psig The answer is 0.0689475728. What is the average pressure on Earth at sea level in bar pressure? 1 atm to mmHgġ atmosphere (atm) = 760.000 mmHg ( millimetres of Mercury) Average atmospheric pressure at sea level The standard constant value used for atmospheric pressure at sea level is 1 atm (standard atmosphere) which equals 101325 pascals in SI units, and is equivalent to 29.9213 inches of mercury. What does one atmospheric pressure equal in inches of mercury? Task: Convert 95 kilopascals to atmospheres (show work) Formula: kPa ÷ 101.325 atm Calculations: 95 kPa ÷ 101.325 0.9375771 atm Result: 95 kPa is equal to 0.9375771 atm Conversion Table For quick reference purposes, below is a conversion table that you can use to convert from kPa to atm.
