Enter the value above and the result appears instantly — the calculation runs entirely in your browser. Formula: value × 145.038.

What is the exact megapascals to psi conversion factor?

1 megapascal = 145.038 psi (shown to 6 significant figures — the converter itself computes at full precision). The reverse factor is 1 pound per square inch = 0.00689476 megapascals.

What are some common megapascals to psi conversions?

1 MPa = 145.038 psi; 10 MPa = 1,450.38 psi; 100 MPa = 14,503.8 psi. Use the full conversion table below for more reference values.

Is PSI the same as psia?

No. PSI usually means gauge pressure (psig) — the difference between the measured pressure and the surrounding atmosphere, which is why a tire reads 0 psi when flat. Absolute pressure (psia) includes atmospheric pressure (~14.7 psi at sea level). This converter converts between pressure magnitudes; it does not add or remove the atmospheric baseline.
