Is it because they are used by the manometer
Pascals, KiloPascals, inches of mercury (inHg), millimeters of mercury (mmHg), and pounds per square inch (PSI) are several common units of pressure. Some others are: Bar, Torr, Atmospheres.
456 Torr is equivalent to 0.601 standard atmospheres. This conversion is done by dividing the pressure in Torr by 760 (the number of Torr in 1 standard atmosphere).
380 mm is equivalent to approximately 0.39 atmospheres.
24.34 inches of Mercury is equivalent to 823.86 torr.
500 mmHg or 500 torr is a gas pressure approximately 66% of the standard sea level air pressure of 760 torr ... it is the air pressure one would find at an altitude of approximately 3km or 10000 feet ... at sea level, 500 torr would be considered a partial vacuum of 0.66 atm.
Millimeters of mercury or Torr
Pascals, KiloPascals, inches of mercury (inHg), millimeters of mercury (mmHg), and pounds per square inch (PSI) are several common units of pressure. Some others are: Bar, Torr, Atmospheres.
Equals 101,325 pascals, 101.325 kpascals, 760 mm of Mercury, and/or 1 atmosphere
600 Torr (1 atm/760 Torr) = 0.789 atmospheres ================
456 Torr is equivalent to 0.601 standard atmospheres. This conversion is done by dividing the pressure in Torr by 760 (the number of Torr in 1 standard atmosphere).
380 mm is equivalent to approximately 0.39 atmospheres.
1 atm = 760 torr 2.2 atm X 760 torr/ 1 atm = 1672 torr i believe, i did the math in my head very quickly.
there are several, like Pascals, mm of mercury, atmospheres, bars, torr, etc.
24.34 inches of Mercury is equivalent to 823.86 torr.
There are 760 torr in 1 inch of mercury. Therefore, 28.5 inches of mercury is equal to 28.5 x 760 = 21660 torr.
One atmosphere (ATM or torr) is equal to 760 millimeters of mercury (mmHg's)
1 atmosphere pressure = 760 torr655 torr / ( 760 torr / ATM) = 0.86184 ATMIf you're not sure whether to multiply or divide when doing conversions, do this:655 torr . 1 ATM------------ * ---------1. . 760 torrThe formatting did not display exactly as I wanted it to appearThis is read like a fraction. Since 1 ATM = 760 torr, the numerator and denominator are equal, so it's like just multiplying by 1 and won't change the value.The torr units in numerator/denominator cancel out, and the only unit remaining is atmospheres.
