Enter the value above and the result appears instantly — the calculation runs entirely in your browser. Formula: value × 760.

What is the exact atmospheres to mmhg conversion factor?

1 atmosphere = 760 mmhg (shown to 6 significant figures — the converter itself computes at full precision). The reverse factor is 1 millimeter of mercury = 0.00131579 atmospheres.

What are some common atmospheres to mmhg conversions?

1 atm = 760 mmHg; 10 atm = 7,600 mmHg; 100 atm = 76,000 mmHg. 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.
