What does an atmospheric pressure of 760 mmHg mean?
millimeters of mercury
At sea level, a mercury column will rise a distance of 760 mm. This atmospheric pressure is reported as 760 mmHg (millimeters of mercury). At higher altitudes, the atmospheric pressure is decreased and so the column of mercury will not rise as high. Atmospheric pressure is slightly dependent on weather conditions.
What is normal atmospheric pressure in kPa?
Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.
What is the difference between mmHg and kPa?
A pressure measured in millimetres of mercury can be converted to a kilopascals reading using the following conversion factor calculation: 1 kPa = 1000 pascals (Pa) 1 mmHg = 133.322 pascals (Pa)…kPa pressure related products.
What is normal atmospheric pressure in mmHg?
Standard atmospheric pressure is called 1 atm of pressure and is equal to 760 mmHg and 101.3 kPa. Atmospheric pressure is also often stated as pounds/square inch (psi).
What is mmHg in vacuum?
A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322387415 pascals. It is denoted mmHg or mm Hg.
What is standard pressure in mmHg?
Standard atmospheric pressure is called 1 atm of pressure and is equal to 760 mmHg and 101.3 kPa.
What is the pressure of 760 mmHg when expressed in units of ATM?
Standard atmospheric pressure is called 1 atm of pressure and is equal to 760 mmHg and 101.3 kPa. Atmospheric pressure is also often stated as pounds/square inch (psi). The atmospheric pressure at sea level is 14.7 psi. Lot more interesting detail can be read here.
How to convert 760 mmHg to atmospheres easily?
You are currently converting Pressure units from Millimeter Mercury (0°C) to Atmospheres. 760 Millimeter Mercury (0°C) (mmHg) =. 1 Atmospheres (atm) Millimeter Mercury (0°C) : 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.
How to convert mmHg to ATM and KPA?
Step 1: List the known quantities and plan the problem. Use conversion factors from the equivalent pressure units to convert from mmHg to atm and from mmHg to kPa. Step 2: Solve.
How is 760 mm Hg equal to 760 mmHg?
The air pressure on the far side keeps the mercury raised up to 760 mm higher than the open side, exactly equal to the force from the weight of that column. So, while 760 mm Hg (or 760 torr) is not actually a pressure, it is a convenient measure when we are using that kind of device.
