Why is millimeter mercury defined at 0°C important?

Millimeter mercury (mmHg) is defined at 0°C to standardize the pressure exerted by mercury columns under standard gravity, ensuring consistent measurements.

Can I use this tool for all pressure measurements?

This tool is designed specifically for converting psi to mmHg; other pressure unit conversions need different tools or methods.

Does this conversion consider temperature and gravity variations?

No. The conversion assumes mmHg at 0°C and standard gravity, so variations in temperature and local gravity can affect accuracy.

What Is This Tool?

This tool converts pressure measurements from pound-force per square inch (psi), an imperial unit commonly used in engineering, to millimeter mercury (mmHg) defined at 0°C, which is widely applied in clinical and laboratory settings.

How to Use This Tool?

Enter the pressure value in pound-force per square inch (psi)
Select 'pound-force/square inch' as the input unit and 'millimeter mercury (0°C)' as the output unit
Click the convert button to obtain the equivalent pressure in mmHg
Review the result and apply it according to your specific application needs

Key Features

Converts psi to mmHg based on the exact conversion rate of 1 psi = 51.7150754803 mmHg
Supports pressure unit translation for automotive, hydraulic, clinical, and laboratory contexts
Browser-based and straightforward to use without requiring additional software
Facilitates interoperability between mechanical system measurements and medical or scientific readings

Examples

5 psi equals 5 multiplied by 51.7150754803, resulting in approximately 258.575 mmHg
10 psi corresponds to 10 times 51.7150754803, which is about 517.151 mmHg

Common Use Cases

Checking automotive tire pressure and hydraulic or pneumatic system specifications using psi and converting to clinical pressure units
Reading and reporting blood pressure measurements in millimeter mercury during medical examinations
Laboratory manometry and reporting vapor or partial pressures in scientific research
Translating moderate vacuum or barometric pressures between engineering and environmental fields

Tips & Best Practices

Ensure you use this conversion when translating mechanical pressure readings to clinical or laboratory units for accuracy
Be aware that mmHg is defined at a temperature of 0°C; temperature variations can affect precision
Consider local gravity variations are not accounted for in this conversion, which assumes standard gravity
Confirm the context of pressure measurement to avoid confusion since psi and mmHg serve different fields

Limitations

Conversion precision may be affected by changes in temperature due to mmHg definition at 0°C
Standard gravity is assumed, so local variations in gravity are not considered
Psi and mmHg represent pressures in different applications, so incorrect context can lead to misinterpretation
