How do you convert MPa to PSI?

Multiply MPa by 145.03773773 to get PSI. Example: 0.7 MPa ≈ 101.5264 PSI.

How do you convert PSI to MPa?

Divide PSI by 145.03773773 to get MPa. Example: 200 PSI ≈ 1.3790 MPa.

Does this converter handle gauge vs absolute pressure?

This tool converts units only. Make sure your input is consistently gauge (MPa(g)/psig) or absolute (MPa(a)/psia) before converting.

Q: Is MPa the same as bar?

No. 1 MPa = 10 bar. PSI is common in North America, while MPa is common in international engineering documentation.

This page helps you convert MPa to PSI (megapascal to pounds per square inch) instantly, and also convert PSI to MPa. You’ll find the conversion formula, worked examples, and a practical table commonly used when reading air compressor pressure ratings and pneumatic system specifications.

Factor: 1 MPa = 145.03773773 PSI Decimals

Common reference points: 0.7 MPa ≈ 101.5 PSI, 1.0 MPa ≈ 145.0 PSI, 1.6 MPa ≈ 232.1 PSI.

Air compressor note: this tool converts units only. If your datasheet uses psig / MPa(g) (gauge) or psia / MPa(a) (absolute), keep the same reference type before comparing specifications.

Formula (Megapascal to PSI)

Use these formulas when you need to convert pressure units quickly in engineering documents, compressor nameplates, and pneumatic manuals.

PSI = MPa × 145.03773773

MPa = PSI ÷ 145.03773773

Example: 0.8 MPa × 145.03773773 = 116.0302 PSI (rounded by your selected decimals).

When MPa vs PSI Appears in Compressor Specs

PSI is widely used in North America, while MPa is common in international standards and industrial documentation. Converting MPa to PSI helps buyers compare working pressure, rated pressure, and tool requirements across regions.

Related quick conversions: 1 MPa = 10 bar, and 1 bar ≈ 14.5038 PSI (useful when reading bar-based compressor spec sheets).

FAQ: MPa and PSI

What is 0.7 MPa in PSI?

0.7 MPa is approximately 101.5264 PSI (rounded by the selected decimals). This value appears often in compressor working pressure specs.

What is 1 MPa in PSI?

1 MPa is approximately 145.0377 PSI.

What is 200 PSI in MPa?

200 PSI is approximately 1.3790 MPa.

Does changing MPa to PSI change the actual pressure?

No. It’s the same pressure expressed in different units. Converting helps compare specifications across regions and datasheets.
