⚙️ MPa → psi Conversion
Translate high-pressure MPa readings into imperial psi.
Many engineering specifications list pressures in MPa, while shop-floor equipment and North American suppliers expect psi. This converter bridges that gap instantly.
1 MPa equals
145.03774 psi
Kips per square inch: 0.145038 ksi
psig (gauge): 130.34179 psig
How to Use This Calculator
Enter MPa value
Type the system pressure measured in megapascals.
Read psi
The converter multiplies by 145.038 to deliver pounds per square inch.
Use supporting units
ksi and psig outputs help with structural or gauge-pressure contexts.
Formula
psi ≈ MPa × 145.037738
ksi = psi ÷ 1,000
psig = psi − 14.6959
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Converting MPa to psi by hand is tedious and error-prone. This tool uses the exact conversion factors defined in the common engineering standards, keeping QA reports and procurement specs consistent.
Additional ksi and psig values ensure compatibility with structural and gauge-based documentation without manual math.
Frequently Asked Questions
Is the conversion exact?
Yes. The psi figure uses the precise MPa to psi factor (1 MPa = 145.037738 psi).
Why include psig?
psig subtracts atmospheric pressure, matching what many gauges display.
Can I convert psi back to MPa?
Divide psi by 145.037738 to return to MPa.
Does temperature affect the conversion?
Unit conversions are temperature-independent; only material properties or gauge readings may vary.
