mmHg to kPa converter
1 mmHg = 0.133322 kPa
And 1 kPa = 7.50062 mmHg. Millimetres of mercury to kilopascal.
Formula
kPa = mmHg × 0.133322
A reading of 15 mmHg is 15 × 0.133322 = 1.99984 kPa.

About these units
mmHg (millimetres of mercury): Blood pressure and vacuum gauges, using the conventional 13.5951 g/cm³ mercury.
kPa (kilopascal): Common for HVAC, building ventilation and low-pressure gas work.
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
