Example: standard atmosphere to millimeter of mercury

Starting value Increment Accuracy

To convert standard atmosphere to millimeter of mercury, multiply by 759.999892.

1 atm = 759.999892 mmHg

Example: 1 standard atmosphere = 759.999892 millimeter of mercury

One atmosphere is not exactly one bar: 1 atm = 1.01325 bar = 101.325 kPa. There is also the technical atmosphere (1 kgf/cm²) at about 0.981 bar. The ~1% differences rarely matter day to day, but engineering and diving calculations need the right unit.
Blood pressure uses mmHg (120/80) and weather reports use hPa (around 1,013), different units that must not be mixed: 760 mmHg = 1,013.25 hPa. One mmHg is about 1.33 hPa.
