Or, you can find the single factor you need by dividing the A factor by the B factor.įor example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into Pascals then divide by the factor for B to convert out of Pascals. To convert from Pa into units in the left columnĭivide by the value in the right column or, multiply by the reciprocal, 1/x.ĥ00000 Pa / 100000 = 5 bar Gas, Air 500 psi 3 to 250 psi 9 ranges 48,000 scfh Cv 12. Multiply by the conversion value in the right column in the table below.ĥ bar * 100000 = 500000 Pa Nm3 (normal cubic meter) gas measured at 1 atmosphere and 0C. Here is the formula: Value in pounds per square inch value in atm × 14.695948803581 Suppose you want to convert 65 atm into pounds per square inch. To simply convert from any unit into pascals, for example, from 5 bar, just 1 atm 14.696 PSI 2 atm 29.392 PSI 3 atm 44.0878 PSI 4 atm 58.784 PSI 5 atm 73.480 PSI 6 atm 88.176 PSI 7 atm 102.872 PSI 8 atm 117.568. To calculate a standard atmosphere value to the corresponding value in psi, just multiply the quantity in atm by 14.695948803581 (the conversion factor). Where S is our starting value, C is our conversion factor, and To convert X pounds per square inch to atmospheres you should use the following conversion. #Atm to psi how to#How to Convert Units of PressureĬonversions are performed by using a conversion factor. By knowing the conversion factor, converting between units can become a simple multiplication problem: psi to atm conversion factor is 0.06804596 1 psi 0.06804596 atm. Some are obvious, such as pounds per square inch, but even the SI standard Pascal is actually an expression of one Newton per square meter. Since pressure is derived from force and area, many units for pressure directly relate force to area. How many pounds per square inch are there in 1 standard atmosphere You can quickly get the value of 1 atm in psi by multiplying 1 atm by 14.6959. 1 pascal is equal to 9.8692326671601E-6 atm, or 0.00014503773800722 psig. 1 Atm to Psi conversion calculator converts 1 atm into pounds per square inch (psi) and also psi into atm. You can view more details on each measurement unit: atm or psig The SI derived unit for pressure is the pascal. psi to atm formula atm psi 0.06804596379 atm psi / 14. To convert psi to atm, multiply the psi value by 0.06804596379 or divide by 14.6959488. We assume you are converting between atmosphere standard and pound/square inch gauge. 1 Psi (pound force per square inch) is equal to 0.06804596379 atm. Where P is equal to pressure, F is the normal force and A is area. How many atm in 1 psig The answer is 0.068045963779916. More pages related to measurement unit technical terms.Pressure is a scalar quality reflecting how force acts on a surface. Use the pressure converter page to convert many different values to and from technical atmosphere units. To convert any pressure unit into Technical Atmospheres click on the relevant unit below. Technical Atmosphere is some times written as ‘ata’ which is the short way of writing ‘at absolute’.Įquivalent values for 1 at in other pressure units can be found in the list below. However the unit has been largely phased out and the average atmospheric pressure is now mostly defined as 1 atm (101325 Pa) for weather and aviation or more coomonly 1 bar (100,000 Pa) for industrial and general purposes. How many pounds-force per square inch in an atmosphere: If p atm 1 then. This web app graphs the barometric pressure forecast and history of any location, along with relevant current weather data such as temperature, humidity and. The at pressure unit can be occasionally found on water resistant watches to indicate the maximum depth rating, particularly on European brands. 1 Technical Atmosphere is defined as being exactly equal to 98,066.5 pascals. Technical Atmosphere is similar although not the same value as the standard atmosphere pressure unit (atm) and both have been used historically to relate a pressure value to multiples of atmospheric pressure.
