How to use
- Enter a value in the Pascals field.
- The Millimeters Of Mercury figure appears immediately — no button to press.
- Typing in the Millimeters Of Mercury field converts back to Pascals the same way.
- Use the reference table for the values that come up most often.
Pascals to Millimeters Of Mercury formula
To convert pascals to millimeters of mercury, multiply by 0.00750061576.
mmHg = Pa × 0.00750061576
Why this factor: the pascal and the millimeter of mercury are both defined against the pascal, so dividing one definition by the other gives 0.00750061576 directly. Both definitions are set out in full below.
To go the other way, divide by 0.00750061576 — or use the Millimeters Of Mercury to Pascals converter, which is the same calculation reversed.
Worked example
Given 32 Pa, multiplying by 0.00750061576 yields 0.24002 mmHg.
32 Pa × 0.00750061576 = 0.24002 mmHg
The converter above does this for any value you type, in either direction.
What is a pascal?
The pascal is the SI unit of pressure — one newton of force spread over one square meter.
Definition: Defined as 1 N/m². Named after Blaise Pascal.
Where it is used: Scientific and engineering pressure calculations, and weather pressure in hectopascals.
Worth knowing: A single pascal is a very small pressure, which is why weather reports use hectopascals and engineering uses kilopascals.
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.
Pascals vs Millimeters Of Mercury
The pascal is an SI 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.
Frequently asked questions
How many millimeters of mercury are in a pascal?
One pascal equals 0.00750061576 millimeters of mercury.
What is the formula to convert pascals to millimeters of mercury?
