Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. The molar volume of a gas expresses the volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions. It is approximately equal to Earth's atmospheric pressure at sea level.Ĭonversion calculator for all types of measurement units. kPammHg 1 kPa 7.500617 mmHg kPainHg 1 inHg 3.3863752577878 kPa kPaInch mercury (60F) coefficient: 0.296134 kPainAg 1 kPa 4.014742 inAg kPaftAg 1 ftAg 2.9889826100992 kPa kPaatm 1 atm 101.32499766353 kPa » Centimeter mercury (0 C) Conversions: cmHgpa 1 cmHg 1333.223653 pa cmHgkPa 1 cmHg 1. 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). The unit is named after Evangelista Torricelli, Italian physicist and mathematician, for his discovery of the principle of the barometer in 1643. It is the atmospheric pressure that supports a column of mercury 1 millimetre high. The torr (symbol: Torr) or millimetre of mercury (mmHg) is a non-SI unit of pressure. Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types.You can do the reverse unit conversion fromĪtm to mm of mercury, or enter any two units below: Enter two units to convert From: You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. It is approximately equal to Earth's atmospheric pressure at sea level.Ĭonversion calculator for all types of measurement units. Millimeter mercury (0 c) Standard atmosphere Conversion Table. Piston engine aircraft with constant-speed propellers also use inHg to measure manifold pressure, which is indicative of engine power produced. Begin: 0 5 10 15 20 30 40 50 60 70 80 90 100. The resulting altimeter readings are known as flight levels. This makes one atmosphere nearly equal to one bar, specifically: 1 atm 1.01325 bar. A bar is a pressure unit defined as 100 kilopascals.

Atmosphere originally was a unit related to the air pressure at sea level.It was later defined as 1.01325 x 10 5 pascals.

742 mmhg to atm how to#

It is defined as the pressure exerted by a column of mercury of 1 inch in height at 32 ☏ (0 ☌) at the standard acceleration of gravity.Īircraft operating at higher altitudes (above 18,000 feet) set their barometric altimeters to a standard pressure of 29.92 inHg or 1,013.2 hPa (1 hPa = 1 mbar) regardless of the actual sea level pressure, with inches of mercury used in the U.S. This example problem demonstrates how to convert the pressure units bar (bar) to atmospheres (atm). It is still widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere. Inches of mercury or inHg is a non-SI unit for pressure. Solution: As per the question: Pressure Reading, P 742 mmHg. the reading of the barometer is equal to 98.9 kPa. You can do the reverse unit conversion fromĪtm to in Hg, or enter any two units below: Enter two units to convert From: we know, 760 mm Hg 1.013 x 10 Pa 0.989 x 10 Pa 98.9 x 10³ Pa 98.9 kPa. 742 Millimeter Mercury (0C) (mmHg) 0.97632 Atmospheres (atm) Visit 742 Atmospheres to mmHg Conversion Millimeter Mercury (0C) : Millimeter of mercury is a small pressure unit which represents the pressure pushing down due to gravity of any volume of liquid mercury which is 1mm high.
