1. What is a PSI to mmHg Calculator?

Definition: This calculator converts pressure values between PSI (pounds per square inch) and mmHg (millimeters of mercury), as well as other common pressure units like Pa, bar, kPa, MPa, at, atm, Torr, hPa, and inHg.

Purpose: It helps engineers, scientists, and technicians convert pressure measurements for various applications, such as medical, industrial, and environmental systems, ensuring accurate unit compatibility.

2. How Does the Calculator Work?

Calculations are based on standard pressure unit conversions using Pascals (Pa) as the intermediate SI unit:

\[ P_{\text{target}} = P_{\text{source}} \times \frac{\text{Conversion factor to Pa (source)}}{\text{Conversion factor to Pa (target)}} \]

Unit Conversions:

Unit	Conversion to Pa
psi (Pounds per square inch)	1 psi = 6894.76 Pa
Pa (Pascals)	1 Pa
bar	1 bar = 100,000 Pa
kPa (Kilopascals)	1 kPa = 1000 Pa
MPa (Megapascals)	1 MPa = 1,000,000 Pa
at (Technical atmospheres)	1 at = 98,066.5 Pa
atm (Standard atmospheres)	1 atm = 101,325 Pa
Torr	1 Torr = 133.322 Pa
hPa (Hectopascals)	1 hPa = 100 Pa
mmHg (Millimeters of mercury)	1 mmHg = 133.322 Pa
inHg (Inches of mercury)	1 inHg = 3386.39 Pa

Explanation: The calculator converts the input pressure to Pascals, then to the target unit, ensuring accurate and consistent results.

3. Importance of Pressure Unit Conversion

Details: Accurate pressure unit conversion is essential for ensuring compatibility across different systems, such as medical devices (e.g., blood pressure monitors using mmHg) and industrial applications (e.g., PSI in engineering).

4. Using the Calculator

Tips: Enter a Pressure Value, select the Source Unit (e.g., PSI), and choose the Target Unit (e.g., mmHg). Results include the converted pressure in the selected target unit.

5. Notes

Notes: Pressure values must be non-negative. The calculator uses standard conversion factors, but results may vary slightly due to rounding or specific environmental conditions. Ensure the units match your application requirements.
