What this calculator does
Converts a measurement given in millimetre of mercurys into kilopascals using the defined conversion factor.
What your result means
The same quantity expressed in kPa instead of mmHg. Nothing about the measurement itself changes.
Formula and working
kPa = mmHg × 0.1333223874
- 1
Start with your value
100 mmHg

Result
100 mmHg = 13.332239 kPa
Frequently asked questions
Symbols and assumptions
- mmHg
- Input unit — millimetre of mercury
- kPa
- Output unit — kilopascal
- Pa
- Base unit used internally for pressure and stress
- • Both units measure pressure and stress, so the physical quantity is unchanged by the conversion.
- • The relationship is exactly linear: 1 mmHg = 0.1333223874 kPa.
- • Values are converted through the SI base unit for this quantity rather than pair by pair.
Sources and review

- • A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
- • Displayed figures are rounded for readability; the full stored precision of the kPa value is used in every onward calculation.
