The pascal (Pa) is the SI (International System of Units) derived unit of pressure, defined as one newton per square meter. It is a fundamental unit used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The pascal is widely recognized in scientific and engineering fields, making it essential for accurate pressure measurement.
The pascal is standardized by the International System of Units (SI) and is used globally in various applications, including meteorology, engineering, and physics. It provides a consistent framework for measuring pressure, ensuring that data can be compared and understood universally.
The pascal was named after Blaise Pascal, a French mathematician, physicist, and inventor who made significant contributions to fluid mechanics and pressure measurement in the 17th century. The unit was officially adopted in 1971 by the General Conference on Weights and Measures (CGPM) to honor Pascal's legacy and to provide a coherent system for measuring pressure.
To understand how to convert pressure units, consider an example where you want to convert 1 bar to pascal. Since 1 bar is equal to 100,000 pascals, the conversion is straightforward: [ 1 \text{ bar} = 100,000 \text{ Pa} ]
The pascal is commonly used in various fields:

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.
