WebAnswer (1 of 2): The pressure of a gas is often measured in different units such as atmospheres (atm), millimeters of mercury (mmHg), or pascals (Pa). One atmosphere is defined as the pressure that results from the weight of the Earth's atmosphere on its surface, and is approximately equal to 101... WebThe torr (symbol: Torr) is a traditional unit of pressure, now defined as exactly 1/760 of a standard atmosphere, which in turn is defined as exactly 101325 pascals. Thus one torr is exactly 101325/760 ≈ 133.3 pascals. This tool converts torr to millimeters of mercury (torr to mmhg) and vice versa. 1 torr = 1 millimeters of mercury. The user ...
Millimeters of mercury to Atmospheres conversion
WebThe millimeter of mercury by definition is 133.322 387 415 Pa [5] ( 13.5951 g/cm3 × 9.806 65 m/s2 × 1 mm ), which is approximated with known accuracies of density of mercury and standard gravity . The torr is defined as 1 760 of one standard atmosphere, while the atmosphere is defined as 101 325 pascals. Web1 atmospheres to millimeters of mercury = 759.99988 millimeters of mercury 2 atmospheres to millimeters of mercury = 1519.99975 millimeters of mercury 3 atmospheres to millimeters of mercury = 2279.99963 millimeters of mercury 4 atmospheres to millimeters of mercury = 3039.99951 millimeters of mercury challice way sw2
What is a Mercury Barometer? (with pictures) - All the Science
WebThe millimeter of mercury by definition is 133.322 387 415 Pa ( 13.5951 g/cm3 × 9.806 65 m/s2 × 1 mm ), which is approximated with known accuracies of density of mercury and gravitational acceleration. The torr is defined as 1∕760 of one atmosphere, while the atmosphere is defined as 101.325 kPa. Therefore, 1 Torr is equal to 101 325∕760 Pa. WebMore information from the unit converter. How many atm in 1 mm of mercury? The answer is 0.0013157896866519.
