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 millimeter of water (mmH₂O) is a unit of pressure defined as the pressure exerted by a column of water exactly 1 millimeter high at standard gravity. It is commonly used in various fields, including engineering, meteorology, and fluid mechanics, to measure low pressures, particularly in applications involving water or other fluids.
The millimeter of water is part of the metric system and is standardized to ensure consistency across scientific and engineering applications. It is often used in conjunction with other pressure units such as pascal (Pa) and bar, allowing for easy conversion and comparison.
The concept of measuring pressure using a column of liquid dates back to the work of Blaise Pascal in the 17th century. The millimeter of water has evolved as a practical unit for measuring pressure in various industries, especially where low-pressure measurements are critical, such as in HVAC systems and laboratory settings.
To convert a pressure reading from millimeters of water to pascals, you can use the following formula: [ 1 , \text{mmH₂O} = 9.80665 , \text{Pa} ] For example, if you have a pressure of 100 mmH₂O, the equivalent pressure in pascals would be: [ 100 , \text{mmH₂O} \times 9.80665 , \text{Pa/mmH₂O} = 980.665 , \text{Pa} ]
Millimeters of water are widely used in various applications, including:
