About the Pressure tool
Convert any pressure unit to any other live as you type — pascals, bar, psi, atmospheres, mmHg/Torr and inches of mercury, with exact conversion factors per SI definitions.
Psi dominates US tire gauges and pipe pressures, while meteorology uses hPa/mbar (identical units) — this converter bridges both without mental math.
