![]() Psi to Atmosphere Conversion Example Task: Convert 75 psi to atmospheres (show work) Formula: psi ÷ 14.695948775 atm Calculations: 75 psi ÷ 14.695948775 5. Its normally reserved for devices designed to be used underwater, and in most cases, 1 ATM is. Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. Next, lets look at an example showing the work and calculations that are involved in converting from pounds per square inch to atmospheres (psi to atm). proof - its just not tested to that standard. You can find metric conversion tables for SI units, as well as English units, currency, and other data. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi.Ĭ provides an online conversion calculator for all types of measurement units. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. 1 psi 0.068046 atm psi to atm 1 psi 0.0689476 bar psi to bar 1 psi 2.0360206576 inHg psi to inHg 1 psi 0. At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. By contrast, psia measures pressure relative to a vacuum (such as that in space). Psig (pound-force per square inch gauge) is a unit of pressure relative to the surrounding atmosphere. It is approximately equal to Earth's atmospheric pressure at sea level. It is sometimes used as a reference pressure or standard pressure. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101325 Pa (1.01325 bar). Psig to atm, or enter any two units below: Enter two units to convert From: Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types.You can do the reverse unit conversion from It is the pressure resulting from a force of one pound-force applied to an area of one square inch.Ĭ provides an online conversion calculator for all types of measurement units. The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. Air pressure inside the submarine is 1.00 atm. to open the hatch from the inside, given it is circular and 0.450 m in diameter. Psi to atm, or enter any two units below: Enter two units to convert From: For example, if your tire gauge reads 34 psi (pounds per square inch), then the absolute pressure is 34 psi plus 14.7 psi (P atm in psi), or 48.7 psi (equivalent to 336 kPa). When watchmakers talk about how water resistant your watch is, we will often use bars or atmospheres and if you’re lucky enough to come across a down to earth watchmaker, we might even use feet Here is a broken down list of water resistant measures we use in the. ![]() pressure in atm (pressure in bar) x (1 atm/1.01325 bar) pressure in atm (0.23/1.01325) atm pressure in atm 0.227 atm Answer: The air pressure at cruising altitude is 0.227 atm. ![]() In this case, we want atm to be the remaining unit. You can do the reverse unit conversion from 100 bars 100 atmospheres 3300 feet 1000 meters 1470.0 PSI. Solution: 1 atm 1.01325 bar Set up the conversion to the desired unit will be canceled out.
