Pressure Unit Converter

Convert pressure between pascals, bar, psi, atmospheres, mmHg/Torr, inHg, and related engineering gauges.

What is 1 atm in this tool?

Standard atmosphere is exactly 101,325 Pa (about 1.01325 bar or 14.696 psi) — mean sea-level pressure at the conventional reference.

mmHg vs blood pressure?

Clinical blood pressure is commonly reported in mmHg (Torr-scale). This converter does the unit math only — it is not a medical monitor or diagnosis tool.

Are gauge and absolute pressure distinguished?

No. Values are converted as numeric magnitudes. Gauge (psig) vs absolute (psia) depends on whether your reading already excludes atmosphere — check your instrument documentation.
