The conversions are between units, whichever reference a gauge uses; tyre and weather pressures are normally quoted relative to atmospheric pressure. Torr and mmHg are equal here by definition.
Convert pascals, kilopascals and bar to PSI, atmospheres, torr, millibar and mmHg — for tyres, weather systems, hydraulics, scuba and medical pressures.

Convert pascals, kilopascals and bar to PSI, atmospheres, torr, millibar and mmHg — for tyres, weather systems, hydraulics, scuba and medical pressures.
📖 From the blog: Converting pressure units: PSI, bar, pascals and atmospheres
Car tyres inflated to 32 PSI sit at 2.21 bar — 220.6 kilopascals. Sea-level air pressure is 101.325 kPa.
Result = input × source-unit factor ÷ destination-unit factor. All factors are relative to the same base unit; intermediate values are not rounded.
Pascals, Kilopascals, Bar, Atmospheres, PSI, Torr, Millibar (hPa), mmHg. Read the labels carefully: regional or decimal/binary variants are separate choices.
Pounds of force pressing on each square inch. Tyre figures are gauge pressures — above atmospheric — but the unit conversions are the same either way.
