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 Torr, often denoted as "Torr," is a unit of pressure defined as 1/760 of an atmosphere (atm). It is commonly used in various scientific fields, especially in vacuum measurements and gas pressure. Understanding the Torr is essential for professionals in physics, chemistry, and engineering, as it provides a standardized way to express pressure levels.
The Torr is standardized based on the physical characteristics of mercury. Specifically, it is defined as the pressure exerted by a column of mercury that is 1 millimeter high at the standard acceleration due to gravity. This standardization allows for consistent measurements across different scientific and industrial applications.
The Torr was named after the Italian scientist Evangelista Torricelli, who invented the barometer in the 17th century. His work laid the foundation for understanding atmospheric pressure and vacuum. Over the years, the Torr has evolved to become a widely accepted unit of pressure measurement, particularly in fields that require precise pressure control.
To convert Torr to atmospheres, you can use the following formula: [ \text{Pressure (atm)} = \frac{\text{Pressure (Torr)}}{760} ]
For example, if you have a pressure of 760 Torr, the conversion to atmospheres would be: [ \text{Pressure (atm)} = \frac{760}{760} = 1 \text{ atm} ]
The Torr is primarily used in scientific research, engineering, and various industries where pressure measurements are critical. It is particularly useful in applications involving vacuum systems, gas chromatography, and meteorology.
