Frequently Asked Questions About Millimeters of Mercury to Standard Atmospheres
People often have specific questions about converting from mmHg to atm. Here are the answers to some of the most common conversions and questions people ask about mmHg to atm.
What does mmHg stand for?
An mmHg is a unit of pressure that is defined as equal to the pressure exerted by a column of mercury that is one millimeter high 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 atm?
A Standard atmosphere (atm) is a unit of pressure defined as 101,325 Pa, 760 mmHg, 1.01325 bar, 760 torr, 4.6959 psi, or 1 ata (atmosphere absolute). It is equivalent to the average atmospheric pressure on Earth at sea level.
How do you convert mmHg to atm?
You have two conversion options to convert millimeters of mercury (mmHg) to standard atmospheres (atm). The first option is to divide mmHg by 760, which is the number of mmHg in 1 atm. The second option is to multiple mmHg by 0.0013157894736842. Both approaches will give you the correct solution.
Is atm greater than mmHg?
Yes, one standard atmosphere (atm) is greater than one millimeter of mercury (mmHg). There are 760 mmHg in a standard atmosphere but only 0.0013157894736842 standard atmospheres (atm) in one mmHg.
Is 1 mmHg the same as 760 atm?
No, there are 577,600 mmHg in 760 mmHg. 1 mmHg is equal to 0.0013157894736842 atm.
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 often used inside a laboratory, for meteorology applications, or in aviation so there is a limit on the height of any instrument. For this reason, the density of the liquid used in a manometer is an important practical consideration.
For example, to measure one standard atmosphere of pressure (atm), you only need a column that is 760 mm tall (0.76 meters) if you use mercury as the liquid. On the other hand, if you use a less dense liquid, the required height of the column is greater. In the case of water, you would need a column that is 10 meters high to measure one standard atmosphere!
How do you convert blood pressure to mmHg?
In much of the world, you do not need to convert blood pressure readings to mm Hg. The reason why no conversion is required is that the blood pressure measurement is made in 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.
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.
For example, 76 cm Hg multiplied by 0.013158 equals 1 atm.
What is the relationship between mmHg and kPa?
There are 7.500615758456564 mmHg in 1 kPa. To convert from kPa to mmHg, multiply the number of kPa by 7.500615758456564. If you need to convert from mmHg to kPa, multiply the number of mmHg by 0.133322387415.
The SI unit of pressure is the Pascal, which is why blood pressure readings are taken in kilopascals (kPa) in some countries.
