What does the HG stand for in mmHg?
British Dictionary definitions for mm Hg mmHg. abbreviation for. millimetre(s) of mercury (a unit of pressure equal to the pressure that can support a column of mercury 1 millimetre high)
How do you convert cm Hg to Pascal?
1 cmHg is equal to 1333.2239 pascal.
What pressure in kilopascals and in atmospheres does a gas exert at 385 mmHg?
a temp of 0’C and a pressure of 101.3 kPa or 1 atm. What pressure, in kilopascals and in atmospheres, does a gas exert at 385 mm Hg? 385 mm Hg *x* 1 atm/760 mm Hg= 0.507 atm.
Why do we use Hg for pressure?
Why is Hg used for pressure? Mercury is commonly used in barometers because its high density means the height of the column can be a reasonable size to measure atmospheric pressure. … A barometer using water for instance would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference.
Why is Hg used for pressure?
Mercury is a useful material to use in a manometer because of its high density. This means that a much shorter column is needed compared to water. For instance, the pressure represented by a column of 100 mm of water is just under 7.4 mm of mercury (mmHg).
What is the meaning of 120mm Hg?
In medicine, pressure is still generally measured in millimetres of mercury. These measurements are in general given relative to the current atmospheric pressure: for example, a blood pressure of 120 mmHg, when the current atmospheric pressure is 760 mmHg, means 880 mmHg relative to perfect vacuum.
What is a Hg?
one hundred grams. 1 hectogram is equivalent to 3.527 ounces.
What is 76cm of mercury?
The normal atmospheric pressure is 76 CM of mercury.
What is the meaning of cmHg?
Centimeters of Mercury is a small pressure unit which represents the pressure pushing down due to gravity of any volume of liquid mercury which is 1cm high. 1 centimeter of mercury at zero degrees Celsius equals 1333.22 pascals.
Why is my BP machine reading in kPa?
If your BP monitor shows readings with a decimal point (example: 18.0) this means that it is in kpa mode instead of mmHg mode. To change this, please follow the following steps depending on the model: UAM-710: Turn the BP monitor off (blank display).
