The term mmHg, or millimeters of mercury, is a unit of pressure defined as the pressure exerted by a column of mercury exactly 1 millimeter high at the acceleration of gravity. It is commonly used in various scientific and medical applications, particularly in measuring blood pressure and atmospheric pressure.
The mmHg unit is standardized in the International System of Units (SI) and is equivalent to approximately 133.322 pascals (Pa). This standardization allows for consistent measurements across different scientific disciplines, ensuring accuracy and reliability in data reporting.
The use of mercury in pressure measurement dates back to the 17th century when Evangelista Torricelli invented the barometer. The mmHg unit gained prominence due to its practicality and the density of mercury, which provides a clear and measurable standard for pressure. Over the years, mmHg has been widely adopted in both clinical settings for blood pressure readings and in meteorology for atmospheric pressure measurements.
To convert a pressure reading from mmHg to pascals, you can use the following formula:
[ \text{Pressure (Pa)} = \text{Pressure (mmHg)} \times 133.322 ]
For instance, if you have a pressure reading of 760 mmHg, the equivalent in pascals would be:
[ 760 , \text{mmHg} \times 133.322 , \text{Pa/mmHg} = 101325.2 , \text{Pa} ]
The mmHg unit is primarily used in the medical field to measure blood pressure, where normal readings are typically around 120/80 mmHg. Additionally, it is used in meteorology to report atmospheric pressure, with standard atmospheric pressure defined as 760 mmHg at sea level.

The Torr, often denoted as "Torr," is a unit of pressure defined as 1/760 of an atmosphere (atm). It is commonly used in various scientific fields, especially in vacuum measurements and gas pressure. Understanding the Torr is essential for professionals in physics, chemistry, and engineering, as it provides a standardized way to express pressure levels.
The Torr is standardized based on the physical characteristics of mercury. Specifically, it is defined as the pressure exerted by a column of mercury that is 1 millimeter high at the standard acceleration due to gravity. This standardization allows for consistent measurements across different scientific and industrial applications.
The Torr was named after the Italian scientist Evangelista Torricelli, who invented the barometer in the 17th century. His work laid the foundation for understanding atmospheric pressure and vacuum. Over the years, the Torr has evolved to become a widely accepted unit of pressure measurement, particularly in fields that require precise pressure control.
To convert Torr to atmospheres, you can use the following formula: [ \text{Pressure (atm)} = \frac{\text{Pressure (Torr)}}{760} ]
For example, if you have a pressure of 760 Torr, the conversion to atmospheres would be: [ \text{Pressure (atm)} = \frac{760}{760} = 1 \text{ atm} ]
The Torr is primarily used in scientific research, engineering, and various industries where pressure measurements are critical. It is particularly useful in applications involving vacuum systems, gas chromatography, and meteorology.
