Millimeter of mercury
A millimeter of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high and now defined as precisely 7002133322387415000♠133.322387415 pascals. It is denoted by the symbol "mmHg".
Although not an SI unit, the millimeter of mercury is still routinely used in medicine, meteorology and many other scientific fields.
One millimeter of mercury is approximately 1 Torr, or 1/760 of standard atmospheric pressure. The two units are not exactly equal; however, the difference (less than 0.000017% to be exact) is negligible for most practical uses.
History and definition
Mercury manometers were the first accurate pressure gauges; they are less used today due to mercury's toxicity, the mercury column's sensitivity to temperature and local gravity, and the greater convenience of other instrumentation. They displayed the pressure difference between two fluids as a vertical difference between the mercury levels in two connected reservoirs. For this reason it became customary to measure pressure in "millimeters (or inches) of mercury".
