Worth knowing
millimeter of mercury: The torr and the millimetre of mercury are not identical. The torr is defined as exactly 1/760 of a standard atmosphere, or 133.3223684... Pa, while mmHg is 133.322387415 Pa. They differ by about one part in seven million, which is irrelevant for blood pressure and can matter in precision vacuum metrology. Full definition →
How the conversion works
Multiply by 750.0615758 to go from bar to millimeter of mercury, or divide by it to go back. Every conversion on this site routes through the SI value (Pa) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? millimeter of mercury to bar: 1 mmHg = 0.001333223874 bar.
