🔩 MPa → psig Conversion
Convert absolute MPa readings into gauge pressure.
Gauge pressure excludes atmospheric pressure, which is how most analog gauges report values. This converter helps you translate MPa specs into psig for field work and procurement.
1.5 MPa equals
202.86066 psig
Pounds per square inch (absolute): 217.55661 psi
Kilopascals: 1,500 kPa
How to Use This Calculator
Enter MPa
Type the absolute pressure in megapascals.
Read psig
The calculator subtracts atmospheric pressure to display pounds per square inch gauge.
Compare psi & kPa
Use supporting units to double-check documentation requirements.
Formula
psi = MPa × 145.037738
psig = psi − 14.6959488
kPa = MPa × 1,000
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Equipment specs often cite MPa (absolute), while installation manuals and gauges use psig. This converter accounts for atmospheric pressure so you can answer both requirements without ambiguity.
Additional psi and kilopascal readings confirm the relationship and make it easy to populate reports in multiple unit systems.
Frequently Asked Questions
What is psig?
psig is gauge pressure—psi relative to atmospheric pressure. It equals psi − 14.6959 at sea level.
Is the calculation temperature dependent?
Unit conversions are fixed; only the actual system pressure may change with temperature.
Can I convert psig back to MPa?
Add atmospheric pressure (14.6959) to psig to get psi, then divide by 145.037738.
Why include kPa output?
Kilopascals help when working with SI-based documentation alongside imperial gauges.
