How to Convert mmHg to PSI?
To convert mmHg to PSI, multiply the mmHg value by 0.0193368. This conversion factor is derived from the relationship between standard atmospheric pressure in both units, where 760 mmHg equals 14.696 PSI.
Example 4: Vacuum Reading
- Input Value = 50 mmHg
- Converted Value = 0.97 PSI
- Additional Units = 0.066 atm
- Application = Laboratory Equipment
Example 5: High Pressure System
- Input Value = 1000 mmHg
- Converted Value = 19.34 PSI
- Additional Units = 1.316 atm
- Application = Industrial Process
Formula for mmHg to PSI Conversion
Direct Conversion Formula:
PSI = mmHg × 0.0193368
where:
mmHg = Pressure in millimeters of mercury
0.0193368 = Conversion factor
Using Atmospheric Pressure:
PSI = mmHg × (14.696 ÷ 760)
where:
14.696 = Standard atmospheric pressure in PSI
760 = Standard atmospheric pressure in mmHg
Temperature Correction:
mmHg(corrected) = mmHg × (1 - 0.000182 × (T - 20))
where:
T = Temperature in Celsius
20 = Reference temperature
Example 1: Blood Pressure Reading
- Input Value = 120 mmHg
- Converted Value = 2.32 PSI
- Additional Units = 0.158 atm
- Application = Medical Measurement
Example 2: Standard Atmosphere
- Input Value = 760 mmHg
- Converted Value = 14.696 PSI
- Additional Units = 1.000 atm
- Application = Reference Value
Example 3: Low Pressure System
- Input Value = 500 mmHg
- Converted Value = 9.67 PSI
- Additional Units = 0.658 atm
- Application = Weather Systems
What is mmHg and PSI?
Millimeters of Mercury (mmHg) is a pressure unit representing the height of a mercury column in millimeters under standard gravity. It’s commonly used in Medical Settings for blood pressure measurements and in Meteorology for atmospheric pressure readings.
Pounds per Square Inch (PSI) is a unit measuring pressure as force per unit area in the imperial system. It’s widely used in Engineering, Industrial Applications, and Everyday Measurements like tire pressure.
