🌍 psi → atm Conversion
Compare gauge or absolute psi readings to atmospheric pressure.
Atmospheres provide a useful reference for high- and low-pressure systems. This converter translates psi readings into atm plus SI units.
Atmospheres: 0.999997 atm
Pascals: 101,324.66 Pa
Kilopascals: 101.3247 kPa
How to Use This Calculator
Enter psi value
Provide the pressure you have measured or calculated.
Review atmospheres
The converter divides psi by 14.6959 to display atm.
Use SI references
Pascals and kPa help when working with international standards.
Formula
atm ≈ psi ÷ 14.6959488
Pa ≈ psi × 6,894.757
kPa = Pa ÷ 1,000
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Converting from psi to atmospheres offers an intuitive sense of how pressures compare to ambient conditions. This is especially helpful in discussions about vacuum systems, diving, and aerospace applications.
The calculator leverages precise conversion factors, ensuring the results remain reliable for engineering documentation.
Frequently Asked Questions
Is the conversion exact?
It uses the standard atmosphere definition (1 atm = 14.6959488 psi).
Can I convert atm back to psi?
Multiply atmospheres by 14.6959488 to return to psi.
Does this handle psig?
Enter absolute psi for true atm conversion. Convert psig to psia first if necessary.
Why show Pascals?
Pascals and kPa are the SI units required by many international standards.
