Understanding the Units
* Inches of mercury (inHg) is a unit of pressure often used in meteorology and aviation. It measures the height of a column of mercury that a given atmospheric pressure can support.
* Pascals (Pa) is the standard unit of pressure in the International System of Units (SI).
Conversion Factor
The conversion factor between inches of mercury and pascals is:
1 inHg = 3386.389 Pa
Conversion Formula
To convert inches of mercury to pascals, use the following formula:
Pressure (Pa) = Pressure (inHg) x 3386.389
Example
Let's say you have a pressure reading of 29.92 inHg. To convert this to pascals:
Pressure (Pa) = 29.92 inHg x 3386.389 Pa/inHg
Pressure (Pa) ≈ 101325 Pa
Important Note: The conversion factor is an approximation. The precise value can vary slightly depending on factors like temperature and gravity.
