1. What is the InHg to PSI Conversion?

The conversion between inches of mercury (inHg) and pounds per square inch (PSI) is a common calculation in various scientific and engineering fields, particularly in meteorology and vacuum systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( inHg \) — Inches of mercury
• \( 2.03602 \) — Conversion factor (1 inHg = 0.491154 PSI)

Explanation: The formula converts a pressure measurement from inches of mercury to pounds per square inch using a standard conversion factor.

3. Importance of Pressure Conversion

Details: Accurate pressure conversion is essential in fields like meteorology (for barometric pressure), aviation, HVAC systems, and industrial processes where different pressure units are used.

4. Using the Calculator

Tips: Enter the pressure value in inches of mercury (inHg). The value must be positive. The calculator will automatically compute the equivalent value in pounds per square inch (PSI).

5. Frequently Asked Questions (FAQ)
