🌍 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

1

Enter psi value

Provide the pressure you have measured or calculated.

2

Review atmospheres

The converter divides psi by 14.6959 to display atm.

3

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.
