Bars to Millimeters Of Mercury formula
To convert bars to millimeters of mercury, multiply by 750.061576.
mmHg = bar × 750.061576
Why this factor: the bar and the millimeter of mercury are both defined against the pascal, so dividing one definition by the other gives 750.061576 directly. Both definitions are set out in full below.
To go the other way, divide by 750.061576 — or use the Millimeters Of Mercury to Bars converter, which is the same calculation reversed.
Worked example
Start with 32 bar. Multiply by 750.061576 to get 24001.970427 mmHg.
32 bar × 750.061576 = 24001.970427 mmHg
The converter above does this for any value you type, in either direction.
What is a bar?
A bar is a metric pressure unit chosen to sit very close to atmospheric pressure.
Definition: Exactly 100,000 pascals by definition. Standard atmosphere is 1.01325 bar, so a bar is slightly less.
Where it is used: European tire and hydraulic pressures, diving depth equivalents, and espresso machine ratings.
Worth knowing: Close to one atmosphere but not equal to it — the difference is about 1.3%.
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.
Bars vs Millimeters Of Mercury
The bar 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.
