Kilopascals to Millimeters Of Mercury formula
Converting kilopascals to millimeters of mercury is a single multiplication by 7.50061576.
mmHg = kPa × 7.50061576
Why this factor: the kilopascal and the millimeter of mercury are both defined against the pascal, so dividing one definition by the other gives 7.50061576 directly. Both definitions are set out in full below.
To go the other way, divide by 7.50061576 — or use the Millimeters Of Mercury to Kilopascals converter, which is the same calculation reversed.
Worked example
Take 100 kPa and multiply by the factor 7.50061576: the result is 750.061576 mmHg.
100 kPa × 7.50061576 = 750.061576 mmHg
The converter above does this for any value you type, in either direction.
What is a kilopascal?
A kilopascal is 1,000 pascals, the practical metric pressure unit.
Definition: Exactly 1,000 pascals. Standard atmospheric pressure is 101.325 kPa.
Where it is used: Tyre pressures outside the US, weather reports in Canada, and structural engineering loads.
What is a millimeter of mercury?
A millimeter of mercury is the pressure exerted by a 1 mm column of mercury, still standard in medicine.
Definition: Defined as exactly 133.322387415 pascals.
Where it is used: Blood pressure readings, intraocular pressure, and respiratory gas pressures.
Worth knowing: Blood pressure is universally reported in mmHg even in fully metric countries — one of the most durable legacy units in medicine.
Kilopascals vs Millimeters Of Mercury
The kilopascal is a metric unit while the millimeter of mercury is a specialized unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
