Frequently Asked Questions About Millimeters of Mercury to Torr
People often have specific questions about converting from mmHg to Torr. Here are the answers to some of the most common conversions and questions people ask about mmHg to Torr.
What does mmHg stand for?
An mmHg is a unit of pressure 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 the mmHg pressure measurement in blood pressure readings and a meteorologist’s weather reports in everyday life.
Over time, 760 mmHg became the preferred unit of measure for standard atmospheric pressure. The torr, while still used, is not as well known as millimeters of mercury.
What is Torr?
Torr is a unit of pressure based on an absolute scale. It is defined as 1/760 of a standard atmosphere, which is equivalent to 133.32 Pascals (Pa). The unit is named in honor of the inventor of the barometer, Evangelista Torricelli, who was an Italian physicist and mathematician. He discovered the principle of the barometer in 1644, and the rest is, as we say, a torr.
The abbreviation for torr is Torr, while the unit name is entirely in lower case (torr).
The torr is not part of the International System of Units (SI Units).
How do you convert mmHg to Torr?
To convert millimeters of mercury (mmHg) to torr (Torr), multiply mmHg by 0.999999857533699. The answer resulting from this multiplication will be in terms of torr (Torr).
As an exercise, suppose we want to convert 1 mmHg to Torr. In this calculation example, we multiply 1 mmHg by the conversion factor 0.999999857533699, which equals 0.999999857533699 Torr.
If you need to convert from torr to mmHg then, vice versa, multiply Torr by the conversion factor 1.000000142466321 to solve for mmHg.
Is torr the same thing as mmHg?
No, a Torr is slightly different from mmHg. 1 Torr is equal to 0.999999857533699 mmHg. In the past, one mmHg was equal to one torr, but this changed in 1954 at the 10e Conférence Générale des Poids et Mesures (10th General Conference on Weights and Measures). Today, the difference between the two units is 0.000015%. This change was made because the pressure of mercury depends on both gravity and temperature.
While the Torr and mmHg are not precisely the same, they are often treated as an equivalent unit of pressure.
How many torr are in mmHg?
There are 1.000000142466321 Torr in one mmHg. While Torr and mmHg are nearly equivalent, there is a difference of 0.000015%. While this is a slight difference, you should account for calculations and conversions requiring precision.
What units make up a torr?
Torr units can be used with prefixes to denote smaller values. In descending order, the different units of torr are torr (Torr), centitorr (cTorr), millitorr (mTorr), microtorr (uTorr), nanotorr (nTorr), picotorr (pTorr), femtotorr (fTorr), attotorr (aTorr), zeptotorr (zTorr), and yactotorr (yTorr).
What is the SI unit of torr?
The SI unit of pressure is the Pascal, which is defined as one Newton per square meter (N/m2). There are 0.0075006 torr in one Pascal.
Is blood pressure measured in torr?
No, blood pressure is measured in millimeters of mercury (mm Hg) or kilopascals (kPa). Torr, which is a non-SI unit of pressure, is not used to measure blood pressure.
Is psi the same as Torr?
No, pounds per square inch (psi) is not the same as torr (Torr). There are 51.7149325716 Torr in 1 psi.
Can you have a negative torr?
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.
What is the relationship between torr and atm?
One torr (Torr) is equal to 1/760 of a standard atmosphere (atm). Put differently, a standard atmosphere (atm) is 760 times larger than one torr.
How many sig figs are in 760 torr?
There are two significant figures (sig figs) in 760 torr. The ‘7’ and the ‘6’ are sig figs, while the ‘0’ is not. Trailing zeroes are not significant figures.
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 in laboratory, medicine, meteorology, and aviation settings. As a result, there are limits to how high a pressure column can be. Since the density is correlated with the height of a pressure column, 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!
Why do we use torr?
The torr unit is primarily encountered when measuring high vacuum pressures and in pressure calculation questions. The torr is convenient for measuring vacuum pressures because of its relationship to atmospheric pressure. One torr is defined as one standard atmosphere. Partial pressure questions typically involve a mixture of Oxygen, Nitrogen, and Helium gas along with a change in temperature or volume..
That said, 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).
What are the different units of pressure?
Commonly used units of pressure include:
- Megapascals (MPa)
- kilopascals (kPa)
- Pascals (Pa)
- standard atmospheres (atm)
- torr (Torr)
- pounds per square inch (psi)
- pounds per square foot (psf)
- millibar (mbar)
- millimeters of mercury (mmHg), historically measured using a column of mercury.
- inches of mercury (inHg)
- dyne (dyn)
- kilopond per square centimeter (kp/cm2)
- kilogram-force per square millimeter (kgf/mm2)
- kilonewton per square meter (kN/m2)
- newton per square meter (N/m2)
