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 atmosphere (atm) is a unit of pressure defined as being precisely equal to 101,325 pascals (Pa). It is commonly used in various scientific fields, including meteorology, aviation, and engineering, to represent atmospheric pressure. Understanding pressure in terms of atmospheres can help users grasp the concept of pressure in a more relatable manner.
The atmosphere is standardized internationally and is widely recognized in scientific literature. It serves as a reference point for understanding other pressure units, such as bars, pascals, and torr. This standardization allows for consistent communication and calculations across different disciplines.
The concept of atmospheric pressure dates back to the 17th century when scientists like Evangelista Torricelli and Blaise Pascal conducted experiments that led to the understanding of pressure as a force exerted by the weight of air. The term "atmosphere" was adopted in the 19th century, and it has since become a fundamental unit in both physics and engineering.
To convert 2 atm to pascals, you can use the following calculation: [ 2 , \text{atm} \times 101,325 , \text{Pa/atm} = 202,650 , \text{Pa} ] This simple conversion showcases how the atmosphere can be translated into a more universally used unit of pressure.
The atmosphere is commonly used in various applications, such as:
