Inches of Mercury (inHg) is a unit of pressure commonly used in meteorology, aviation, and various scientific applications. It measures the pressure exerted by a column of mercury that is exactly one inch high. This unit is particularly significant in weather forecasting, where atmospheric pressure is a critical factor.
The inch of mercury is standardized based on the gravitational force acting on mercury at a specific temperature. At sea level, standard atmospheric pressure is defined as 29.92 inHg, which is equivalent to 1013.25 hPa (hectopascals) or 101.325 kPa (kilopascals). This standardization allows for consistent measurements across different applications and regions.
The use of mercury in pressure measurement dates back to the 17th century when Evangelista Torricelli invented the barometer. The concept of measuring pressure using a column of liquid was revolutionary and laid the groundwork for modern meteorological instruments. Over time, the inch of mercury became a standard unit in many fields, particularly in the United States, where it is still widely used today.
To convert pressure from pascals (Pa) to inches of mercury (inHg), you can use the following formula:
[ \text{Pressure (inHg)} = \frac{\text{Pressure (Pa)}}{3386.39} ]
For instance, if you have a pressure of 101325 Pa (standard atmospheric pressure), the conversion would be:
[ \text{Pressure (inHg)} = \frac{101325}{3386.39} \approx 29.92 \text{ inHg} ]
Inches of mercury is primarily used in meteorology to report atmospheric pressure. It is also utilized in various engineering applications, including HVAC systems, where precise pressure measurements are crucial for system efficiency and safety.

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.
