Here are the answers to some of the most common conversions and questions people ask about atm to mmHg.<\/span><\/p>\n<h3><b>What does mmHg stand for?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">An mmHg is a manometric unit of pressure that stands for &#8216;millimeters of mercury&#8217;. It is defined as equal to the pressure exerted by a column of mercury that is<\/span><a href=\"https:\/\/en.wikipedia.org\/wiki\/Millimetre_of_mercury#:~:text=A%20millimetre%20of%20mercury%20is,exactly%20133.322387415%20pascals.\"><span style=\"font-weight: 400;\"> one millimeter high<\/span><\/a><span style=\"font-weight: 400;\"> under standard gravity. You will most frequently encounter mmHg from blood pressure readings and barometer data in meteorologists&#8217; weather reports.<\/span><\/p>\n<h3><b>Is atm greater than mmHg?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">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.<\/span><\/p>\n<h3><b>Is mmHg a pressure or a volume?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">An mmhg is a manometric unit of pressure equal to the pressure created by a column of mercury that is one millimeter high. In meteorology, millimeters of mercury (mmHg) are used in weather forecasts and reporting. As outside air pressure increases or decreases, the change in the weight of the pressure on the column of mercury will cause mmHg to rise or fall.<\/span><\/p>\n<h3><b>Why is pressure measured in mmHg?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Historically, pressure measurements were made in millimeters of mercury (mmHg) because<\/span><a href=\"https:\/\/sciencing.com\/dense-liquid-5730281.html#:~:text=Mercury%20is%20the%20densest%20liquid,but%20it%20is%20also%20toxic.\"><span style=\"font-weight: 400;\"> mercury is the densest liquid at room temperature<\/span><\/a><span style=\"font-weight: 400;\">. A dense liquid is helpful for pressure column applications because it minimizes the height needed for a column, which is an important practical concern. A pressure column, also called a manometer, is often used inside a laboratory, so instruments cannot be taller than the ceiling.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">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. That&#8217;s why we measure pressure in mmHg and millimeters of water!<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Other commonly used units of pressure and their abbreviations include pounds per square inch (psi), kilopascals (kPa), inches of water (inH2O), torr (Torr), technical atmosphere (kilograms-force per square cm kgf\/cm2), barad (Ba), and bar (bar). Regardless of the unit of pressure used, pressure is a force exerted on a given area.<\/span><\/p>\n<h3><b>How do you convert atm to cmHg?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">To convert from atm (standard atmospheres) to cmHg (centimeters of mercury), multiply atm by 76. The result will be your answer in atm.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, 1 atm multiplied by 76 equals 76 cmHg.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><b>Conclusion<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">In conclusion, 400 atm equals 304000 mmHg.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">See the related articles below to learn more about converting standard atmospheres to millimeters of mercury.
