🔧 Pa → psi Converter
Translate SI pressure values into imperial psi readings.
Useful for maintenance teams and engineers who receive sensor data in Pascals but need to communicate results in psi.
100000 Pa equals
14.50377 psi
psig (gauge): -0.19218 psig
Kilopascals: 100 kPa
How to Use This Calculator
Enter Pascals
Provide the pressure reading in Pa.
Read psi
The converter divides by 6,894.757 to display pounds per square inch.
Check gauge pressure
psig output subtracts atmospheric pressure, matching most dial gauges.
Formula
psi ≈ Pa ÷ 6,894.757293168
psig = psi − 14.6959488
kPa = Pa ÷ 1,000
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Many sensors and simulation tools default to Pascals, while field crews expect psi. This converter makes it effortless to present data in the unit your audience expects without manual calculation errors.
Gauge pressure (psig) and kilopascals are included so you can cover multiple documentation standards with one conversion.
Frequently Asked Questions
What is psig?
psig represents gauge pressure, meaning psi relative to atmospheric pressure.
How accurate is the conversion?
It uses the precise factor defined by international standards for Pa-to-psi conversion.
Can I convert psi back to Pa?
Multiply psi by 6,894.757293168 to recover Pascals.
Does altitude affect the conversion?
Only the psig adjustment depends on atmospheric pressure. The Pa-to-psi conversion itself is constant.
