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 millibar (mbar) is a unit of pressure that is widely used in meteorology and various scientific applications. It is defined as one-thousandth of a bar, where one bar is equivalent to 100,000 pascals (Pa). The millibar is particularly useful for measuring atmospheric pressure, making it an essential tool for weather forecasting and climate studies.
The millibar is standardized under the International System of Units (SI) and is commonly used in conjunction with other pressure units such as pascals (Pa) and bars. The conversion between these units is straightforward: 1 mbar equals 100 pascals. This standardization ensures that measurements are consistent and reliable across various scientific disciplines.
The millibar was introduced in the early 20th century as a practical unit for meteorological observations. It gained popularity due to its convenience in expressing atmospheric pressure, especially since the average sea-level pressure is approximately 1013.25 mbar. Over the years, the millibar has become a staple in weather reports and scientific research, evolving alongside advancements in technology and measurement techniques.
To convert 1013.25 mbar to pascals, you can use the following formula:
[ \text{Pressure (Pa)} = \text{Pressure (mbar)} \times 100 ]
Thus,
[ 1013.25 , \text{mbar} = 101325 , \text{Pa} ]
The millibar is primarily used in meteorology to report atmospheric pressure. It is also utilized in various scientific fields, including physics and engineering, where pressure measurements are critical. Understanding how to convert between millibars and other pressure units, such as pascals and bars, is essential for accurate data interpretation.
To use the millibar conversion tool effectively, follow these steps:
