Why is pressure measured in mmHg?
Historically, pressures were measured in millimeters of mercury (mmHg) because mercury is the densest liquid at room temperature. A dense liquid is helpful for pressure column applications because it minimizes the height needed for a column.
A pressure column, also called a manometer, is a pressure measurement device. There is a practical height limitation on the pressure column when it is used in confined spaces in laboratories, meteorology, and aviation. For this reason, the density of the liquid used in a manometer is an important practical consideration.
To measure one standard atmosphere of pressure, you would need a column that is 760 mm tall if you were to use mercury as the liquid. On the other hand, if you use a less dense fluid, the required height of the column is greater. In the case of water, you would need a column 10 meters high to measure one standard atmosphere!

What does mmHg stand for?
An mmHg is a non-SI unit of pressure. It is equal to the pressure that is exerted by a one-millimeter-high volume of liquid mercury under standard gravity. It is a manometric unit of pressure and is an abbreviation for millimeters of mercury. You will most frequently encounter mmHg from blood pressure readings and a meteorologist’s weather reports in everyday life.
What is an atm?
A standard atmosphere (atm) is a unit of pressure equal to 101,325 Pa, 101.325 kPa, 760 mmHg, 1.01325 bar, 760 torr, 4.6959 psi, or 1 ata. It is equivalent to the average atmospheric pressure on Earth at sea level.
What is the relationship between mmHg and kPa?
There are 7.500615758456564 mmHg in 1 kPa. To convert from kPa to mmHg, multiply the kPa value by 7.500615758456564. If you need to convert from mmHg to kPa, multiply the mmHg value by 0.133322387415.
The SI unit of pressure is the Pascal, which is why some countries take blood pressure readings in kilopascals (kPa).
Is atm greater than mmHg?
Yes, one standard atmosphere (atm) is greater than one millimeter of mercury (mmHg). There are 760 mmHg in one standard atmosphere but only 0.0013157894736842 standard atmospheres (atm) in one mmHg.
Is 760 mmHg the same as 1 atm?
Yes, 760 mmHg is the same as 1 atm.
Is 1 mmHg the same as 760 atm?
No, there are 577,600 mmHg in 760 atm. 1 mmHg is equal to 0.0013157894736842 atm.
Does 76 mmHg equal 1 atm?
No, 76 mmHg is not equal to 1 atm. Standard atmospheric pressure is defined as 101.325 kPa, or 760 mmHg or 101.325 kPa. 76 mmHg equals 0.1 atm.
Does 1 bar equal to 1 atm?
1 bar is equal to 0.986923 atm.
Is torr and atm the same?
No, torr and atm are not the same. One torr is equal to 1/760 of an atmosphere.
What is atmospheric pressure at sea level in mmHg?
The atmospheric pressure at sea level is 760 mmHg. The pressure caused by the molecules comprising air above us is called atmospheric pressure. This pressure is caused by gravity pulling the air towards the Earth.
How do you convert barometric pressure to atmospheric pressure?
To convert barometric pressure to atmospheric pressure, multiply the barometric pressure in atmospheres (atm) by 760 millimeters of mercury.
How do you convert blood pressure to mmHg?
In countries where blood pressure is reported in kPa (kilopascals), multiply the kPa blood pressure reading by 7.500615758456564. The resulting value will be in mmHg units.
In much of the world, you do not need to convert blood pressure readings to mmHg. The reason why no conversion is required is that the blood pressure measurement is made in mmHg!
Ideal gas law: Can you use mmHg in PV nRT?
Yes, you can use millimeters of mercury (mmHg) in the PV nRT ideal gas equation. The ideal gas constant R has different values depending on the units of pressure, temperature, and volume chosen for the ideal gas equation. When the pressure in a container is measured in mmHg, the value of the ideal gas constant R:
R=62.3 L • mmHG/K • mol where L=liters, mmHg=millimeters of mercury, K=temperature in Kelvin, and mol=moles
What is atm in moles?
According to the Ideal Gas Law, 1 atm is equal to the pressure exerted by 1 mole of a gas occupying a volume of 22.4 liters at 273 degrees Kelvin. This is the temperature and pressure known as standard temperature and pressure (STP).
What unit is equivalent to mmHg?
The unit torr is equivalent to mmHg and is named after the inventor of the barometer, Evangelista Torricelli.
How do you convert cm Hg to atm?
To convert from cmHg (centimeters of mercury) to atm (standard atmospheres), multiply cm Hg by 0.013158. The result will be your answer in atm units.
For example, 76 cm Hg multiplied by 0.013158 equals 1 atm.
How to convert barometric pressure from inches hg to mmHg
To convert from inches of mercury to millimeters of mercury, multiply the inches hg value by 25.4. This is shown in the equation below.
mmHg=inches hg × 25.4
In conclusion, 780 mmHg equals 1.02631579 atm.
