Exactly: 1 millimeter of mercury = 0.019336777459462117 psi. The reverse factor is 1 pound per square inch = 51.71492520387193 mmhg.

1 mmHg = 0.0193368 psi; 10 mmHg = 0.193368 psi; 100 mmHg = 1.93368 psi. 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.
