Here are the answers to some of the most common questions people ask about the Torr and mmHg pressure measurement units.<\/p>\n<h3>What is\u00a0Torr?<\/h3>\n<p>Torr is a unit of pressure based on an absolute scale. It is defined as precisely 1\/760 of a standard atmosphere and is equivalent to 133.32 Pascals (Pa). The unit is named in honor of <a href=\"http:\/\/chemed.chem.purdue.edu\/genchem\/history\/torricelli.html\">Evangelista Torricelli<\/a>, an Italian physicist, mathematician, and discoverer of barometric pressure theory.<\/p>\n<p>Torricelli invented and then demonstrated a mercury barometer to the public in 1644, which subsequently led to the creation of the field of meteorology. He explained the principle that small fluctuations in the height of the mercury column were due to changes in atmospheric pressure. These changes in the pressure exerted by atmospheric pressure are due to weather conditions and can predict the weather.<\/p>\n<p>We have Torricelli to thank for mercury barometers, modern weather reporting, and manometric pressure readings in areas such as physiology, medicine, general chemistry, industrial chemistry, scuba diving, and car tire pressures. Torr is also encountered when it is used to express pressure measurements in a thermodynamic system.<\/p>\n<p>The abbreviation for the unit name torr is Torr, while the unit name is entirely in lowercase (torr). If you see a spelling that uses &#8216;Tor&#8217;, it is not correct but a common mistake. Similarly, you may encounter &#8216;T&#8217; as a symbol for torr, but this is also incorrect. &#8216;T&#8217; is an abbreviation for the tesla unit, which is used to measure the strengths of magnetic fields.<\/p>\n<p>The\u00a0torr\u00a0is not\u00a0part of the International System of Units\u00a0(SI Units).<\/p>\n<h3>What does\u00a0mmHg\u00a0stand for?<\/h3>\n<p>An mmHg is a unit of pressure equal to the extra pressure generated by a column of mercury that is one millimeter high under standard gravity. The unit definition of a millimeter of mercury is that it equals 133.322387415 pascals (Pa), which is derived from the known accuracies of mercury&#8217;s density and standard gravity. In the past, it was defined as the pressure exerted by a one millimeter high column of mercury. The mmHg is a manometric unit of pressure and is an abbreviation for millimeters of mercury. Millimeters of mercury is used to measure atmospheric pressures and benefit from being independent of the volume of the mercury column.<\/p>\n<p>Typical uses of the mmHg pressure measurement include chemistry measurements, general science, blood pressure readings,<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/2589494\/\"> central venous pressure measurements<\/a>, cerebrospinal fluid pressure, intramuscular pressure recordings, gas pressure gauges, and a meteorologist&#8217;s weather reports. Measurements are made using a manometer, such as a barometer or a transducer equivalent.<\/p>\n<p>Over time, 760 mmHg became the preferred definition for standard atmospheric pressure among scientists. Millimeters of mercury are preferred when making most gas pressure measurements. The torr, while still used, is not as well known as millimeters of mercury.<\/p>\n<h3>How do you\u00a0convert\u00a0Torr to mmHg?<\/h3>\n<p>You can use our pressure converter, a conversion table, or conversion factors to convert from Torr to mmHg.<\/p>\n<p>To convert millimeters of torr (Torr) to mercury (mmHg) using conversion factors, multiply the Torr value by 1.000000142466321. The answer resulting from this multiplication will be in terms of mmHg.<\/p>\n<p>The unit conversion formula for Torr to mmHg is:<\/p>\n<p>Torr * 1.000000142466321 = number of mmHg<\/p>\n<p>The torr values cancel, and we are left with an answer in terms of mmHg<\/p>\n<p>An alternative approach is to divide the torr value by 0.999999857533699 to solve for millimeters of mercury. Both the multiplication and division approaches will return the same answer.<\/p>\n<p>If you need to convert from mmHg to Torr then multiply mmHg by the conversion factor 0.999999857533699 to solve for Torr.<\/p>\n<h3>Why do we use torr?<\/h3>\n<p>The torr unit is primarily encountered when measuring high vacuum pressure and vapor pressure. You may also use torr in various pressure, partial pressure, and gas law questions. The torr is convenient for measuring vacuum pressures in physics, engineering, and science applications because of its relationship to atmospheric pressure. One torr is defined as one standard atmosphere.<\/p>\n<p>Partial pressure questions include mixtures of all types of gas, including Oxygen, Nitrogen, Carbon Dioxide, Carbon Monoxide, Helium, and Chlorine gas. A common feature of gas law questions is changes in temperature or volume.<\/p>\n<p>The torr is declining in popularity in favor of the millibar (mbar) for vacuum pressure measurements. The millibar is also known as the hectopascal (hPa).<\/p>\n<h3>Is 760 mmHg equal to 1 torr?<\/h3>\n<p>No, there are 760 Torr in 760 mmHg.<\/p>\n<h3>Is\u00a0torr\u00a0the same thing as\u00a0mmHg?<\/h3>\n<p>No, a Torr is slightly different from mmHg. Due to redefinitions, 1 Torr is equal to 0.999999857533699 mmHg.<\/p>\n<p>One mmHg was equal to one torr in the past, but the accepted definition was changed in 1954 at the 10e Conf\u00e9rence G\u00e9n\u00e9rale des Poids et Mesures (10th General Conference on Weights and Measures). This change was made because the pressure of mercury depends on both gravity and temperature, which leads to fluctuations in atmospheric pressure depending on location. That said, torr still equals one millimeter of mercury if the temperature is zero degrees Celsius (32 degrees Fahrenheit) and the gravitational acceleration is 9.80665 meters per second squared.<\/p>\n<p>Since there is a slight difference (0.000015%) between the two units, it is crucial to be aware of this difference when making unit conversions requiring precision. Otherwise, rounding errors will occur. While a 1:1 ratio between torr and mmHg is commonly used because there is only a small difference between them, it is not precisely correct to use a one-to-one ratio.<\/p>\n<p>While the Torr and mmHg are not precisely the same, the values of the pressure measured are similar. As a result, they are often treated as an equivalent unit of pressure with a one-to-one relationship.<\/p>\n<h3>How many torr is sea level?<\/h3>\n<p>The average atmospheric pressure at sea level is 760 torr.\u00a0Atmospheric pressure at sea level is also called standard atmosphere or standard pressure.<\/p>\n<p>While barometric air pressure decreases with increasing elevation, more factors can affect air pressure. Due to the gravity acceleration constant, the air pressure at sea level varies by location due to elevation, latitude, the Earth&#8217;s rotation, and the non-sphericity of the Earth.<\/p>\n<h3>What is the normal barometric pressure range?<\/h3>\n<p>A normal pressure barometric range is between 735.06 Torr (735.06 mmHg) and 787.57 Torr (735 mmHg). The equivalent pressure range in kilopascals (kPa values) is 98 kPa to 105 kPa.<\/p>\n<h3>What units make up a\u00a0torr?<\/h3>\n<p>Torr units can be used in combinations using prefixes to denote smaller pressure amounts. In descending order, the different unit symbols and prefixes used for torr are:<\/p>\n<ul>\n<li>torr (Torr)<\/li>\n<li>centitorr (cTorr)<\/li>\n<li>millitorr (mTorr)<\/li>\n<li>microtorr (uTorr)<\/li>\n<li>nanotorr (nTorr)<\/li>\n<li>picotorr (pTorr)<\/li>\n<li>femtotorr (fTorr)<\/li>\n<li>attotorr (aTorr)<\/li>\n<li>zeptotorr (zTorr)<\/li>\n<li>yactotorr (yTorr)<\/li>\n<\/ul>\n<h3>What is the SI unit of torr?<\/h3>\n<p>As you may know, the torr is not part of the International System of Units (SI Units). The SI pressure unit is the Pascal (Pa), defined as one Newton per square meter (N\/m2). Pascals are a SI-derived unit of pressure. There is 0.0075006 torr in one Pascal, the standard unit of pressure.<\/p>\n<h3>Is blood pressure measured in\u00a0torr?<\/h3>\n<p>No, blood pressure measurements are made in millimeters of mercury (mm Hg) or kilopascals (kPa). Torr, a non-SI unit of pressure defined as (1\/760) of an atmosphere, is not used to measure blood pressure. You can check this for yourself the next time you check your blood pressure with a blood pressure monitor.<\/p>\n<h3>Is\u00a0psi\u00a0the same as\u00a0Torr?<\/h3>\n<p>No, pounds per square inch (psi) is not the same as torr (Torr). The difference between the two is that there are 51.7149325716 Torr in 1 psi.<\/p>\n<h3>Can you have a negative\u00a0torr?<\/h3>\n<p>You cannot have negative torr because you cannot have negative pressure. Pressure is always equal to or greater than zero. Zero pressure is a perfect vacuum, while we say low pressures are equal to a high vacuum. This means that torr values start at zero and all other values are positive, not negative, direction. For that reason, torr is known as an absolute unit of pressure since it is based on an absolute scale.<\/p>\n<h3>What is the relationship between torr and atm?<\/h3>\n<p>One torr (Torr) equals 1\/760 of a standard atmosphere (<a href=\"https:\/\/www.tipwho.com\/article-category\/atm\/\">atm<\/a>). Put differently, a standard atmosphere (atm) is 760 times larger than one torr. If you need to convert between torr and standard atmosphere, use our Torr to atm conversion calculator. In decimal form, 1\/760 equals 0.0013157894736842.<\/p>\n<h3>How do you convert Torr to atm?<\/h3>\n<p>To convert from Torr to atm, multiply the Torr value by the torr atm conversion factor of 0.0013157894736842 (1\/760). The result will be in terms of atmospheres (atm values). This simple torr atm conversion factor comes from there being 1\/760 atm in one Torr. It&#8217;s entirely up to you whether to use the conversion factor&#8217;s decimal or fraction form to calculate torr to atm.<\/p>\n<p>To convert atm to Torr, meaning vice versa, multiply the atm value by the atm torr conversion factor of 760. The answer is in terms of Torr. The atm torr conversion factor comes from the fact that there are 760 Torr in one standard atmosphere (atm).<\/p>\n<h3>Why is pressure measured in\u00a0mmHg?<\/h3>\n<p>Historically, pressures were measured in millimeters of mercury (mmHg) because liquid 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 in laboratory, medicine, physiology, meteorology, and aviation settings. As a result, there are limits to how high a pressure column can be. Since density is correlated with the height of a pressure column, the density of the liquid used in a manometer is an important practical consideration.<\/p>\n<p>To illustrate the key difference between mercury and other liquids in pressure columns, consider the following 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 (1,000 centimeters of water) to measure one standard atmosphere!<\/p>\n<p>Today, the height consideration for a pressure column is not as important because many manometers, such as the aneroid barometer, do not use liquid to measure pressure.<\/p>\n<p>Modern pressure measurements use force per unit area. While manometric units of pressure are considered obsolete, their use is still commonplace. Other modern units, such as the <a href=\"https:\/\/www.tipwho.com\/article-category\/kpa\/\">kilopascal<\/a>, are preferred for gas pressures because they do not rely on an assumed density or acceleration of gravity. For this reason, car tire pressure gauges are in kPa or psi, which express force per unit area. You can verify this yourself when checking for proper air pressure in your tire, which also improves your gas mileage.<\/p>\n<h3>What are the different units of pressure?<\/h3>\n<p>Commonly used pressure units and their abbreviations include:<\/p>\n<ul>\n<li>Megapascals\u00a0(MPa)<\/li>\n<li>kilopascals\u00a0(kPa)<\/li>\n<li>Pascals\u00a0(Pa)<\/li>\n<li>standard atmospheres (atm)<\/li>\n<li>torr (Torr)<\/li>\n<li><a href=\"https:\/\/www.tipwho.com\/article\/convert-350-kpa-to-psi-pressure-conversion-calculator\/\">pounds per\u00a0square inch\u00a0(psi)<\/a><\/li>\n<li>pounds per\u00a0square foot\u00a0(psf)<\/li>\n<li>bar<\/li>\n<li>millibar (mbar)<\/li>\n<li>decibar (dbar)<\/li>\n<li><a href=\"https:\/\/www.tipwho.com\/article-category\/mmhg\/\">millimeters of mercury\u00a0(mmHg)<\/a>, historically measured using a column of mercury.<\/li>\n<li>inches of\u00a0mercury\u00a0(inHg)<\/li>\n<li>dyne\u00a0(dyn)<\/li>\n<li>kilopond per\u00a0square centimeter\u00a0(kp\/cm2)<\/li>\n<li>kilogram-force\u00a0per square\u00a0millimeter\u00a0(kgf\/mm2)<\/li>\n<li>kilonewton\u00a0per\u00a0square meter\u00a0(kN\/m2)<\/li>\n<li>newton\u00a0per\u00a0square meter\u00a0(N\/m2)<\/li>\n<\/ul>\n<h3>What is the metric unit of distance?<\/h3>\n<p>The metric distance and length unit is the meter.
