kPa to mmHg – convert kilopascals to millimetres of mercury
Convert kPa to mmHg (kilopascals to millimetres of mercury) when you need pressures expressed in the familiar mmHg scale. Ideal for blood pressure, anaesthetics, ventilators and older lab instruments. This page opens the main pressure converter with kPa → mmHg pre-selected.

Use main converter (kPa → mmHg) or switch to mmHg → kPaThe main pressure tool also converts between Pa, bar, mbar, atm and psi.
Quick reference: kPa to mmHg
One kilopascal is about 7.50062 mmHg, so: mmHg = kPa × 7.50062. Examples:
| Pressure (kPa) | Pressure (mmHg, approx.) |
|---|---|
| 1 kPa | 7.50 mmHg |
| 5 kPa | 37.50 mmHg |
| 10 kPa | 75.01 mmHg |
| 16 kPa | 120.01 mmHg |
| 20 kPa | 150.01 mmHg |
| 101.33 kPa | 760 mmHg |
Why convert kPa to mmHg?
kPa to mmHg is helpful when you:
- Interpret blood pressure when your monitor or guidelines use kPa or mmHg only.
- Compare medical or engineering documents that mix SI and legacy units.
- Cross-check ventilator or anaesthetic machine settings between regions.
- Teach or learn how historic mmHg values relate to modern kPa measurements.
