Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. Mercury has a density of 13 g/cm 3 and bromine has a density of 3 g/cm 3. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. a) 753 mm Hg to atm b) 250 torr to mm Hg c) 0 atm to Pa d) 1 kPa to lb/in 2 e) 40 lb/in 2 to mm Hg. Piston engine aircraft with constant-speed propellers also use inHg to measure manifold pressure, which is indicative of engine power produced.Ĭonversion calculator for all types of measurement units. The resulting altimeter readings are known as flight levels. 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. It is still widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere. Slide 1 Gases Chapter 5 Slide 2 Elements that exist as gases at 25 0 C and 1 atmosphere Slide 3 Slide 4 Gases assume the volume and shape of their containers. Inches of mercury or inHg is a non-SI unit for pressure. This small difference is negligible for most applications outside metrology. Task: Convert 325 mmHg to kilopascals (show work) Formula: mmHg x 0.1333223684 kPa Calculations: 325 mmHg x 0.1333223684 43.32977 kPa Result: 325 mmHg is equal to 43.32977 kPa Conversion Table For quick reference purposes, below is a conversion table that you can use to convert from mmHg to kPa. 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%). To convert torr to atm, multiply the torr value by 0.00131578947 or divide by 760. The relationship between the torr and the millimeter of mercury is: 1 Torr (mmHg) is equal to 0.00131578947 atmospheric pressure (atm). The decimal form of this fraction is approximately 133.322368421. Answer : The volume of methane gas at STP is 36.75 mLExplanation :Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law. Therefore, 1 Torr is equal toġ01325/760 Pa. 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.
