Exactly: 1 atmosphere = 0.101325 megapascals. The reverse factor is 1 megapascal = 9.869232667160128 atmospheres.
1 atm = 0.101325 MPa; 10 atm = 1.01325 MPa; 100 atm = 10.1325 MPa. Use the full conversion table below for more reference values.
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.
