You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. Simply type in the pressure measurement in mmHg that you want to convert to Atm. It is approximately equal to Earth's atmospheric pressure at sea level.Ĭonversion calculator for all types of measurement units.
It is sometimes used as a reference pressure or standard pressure. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101325 Pa (1.01325 bar). This small difference is negligible for most applications outside metrology. The difference between one millimeter of mercury and one torr, as well as between one atmosphere (101.325 kPa) and 760 mmHg (101.3250144354 kPa), is less than one part in seven million (or less than 0.000015%). The relationship between the torr and the millimeter of mercury is: The decimal form of this fraction is approximately 133.322368421.

Use this page to learn how to convert between millimeters mercury and atmospheres. Note that rounding errors may occur, so always check the results. The torr is defined as 1/760 of one standard atmosphere, while the atmosphere is defined as 101325 pascals. The millimeter of mercury by definition is 133.322387415 Pa (13.5951 g/cm3 × 9.80665 m/s2 × 1 mm), which is approximated with known accuracies of density of mercury and standard gravity.
