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 kilogram per square meter (kg/m²) is a unit of pressure that quantifies the force exerted by a mass of one kilogram distributed over an area of one square meter. This measurement is crucial in various fields, including engineering, construction, and physics, as it helps in understanding how weight is distributed across surfaces.
The kilogram per square meter is part of the International System of Units (SI). It is derived from the base units of mass (kilogram) and area (square meter). This standardization ensures consistency in measurements across different applications and industries, making it easier for professionals to communicate and collaborate effectively.
The concept of pressure has been studied for centuries, with early definitions dating back to the work of scientists like Blaise Pascal. The kilogram per square meter has evolved as a practical unit of measurement, particularly in the fields of fluid mechanics and material science. Its widespread adoption in engineering practices has made it a fundamental unit for assessing structural integrity and material performance.
To illustrate the use of kg/m², consider a scenario where a 10 kg weight is placed evenly on a surface area of 2 m². The pressure exerted can be calculated as follows:
[ \text{Pressure (kg/m²)} = \frac{\text{Weight (kg)}}{\text{Area (m²)}} = \frac{10 \text{ kg}}{2 \text{ m²}} = 5 \text{ kg/m²} ]
Kilogram per square meter is commonly used in various applications, including:
