Browser-based tool requiring no installation or registration.
Examples
-
Convert 760 millimeter mercury (0°C) to megapascal: 760 × 0.000133322 = 0.10132592 MPa.
-
Convert 500 millimeter mercury (0°C) to megapascal: 500 × 0.000133322 = 0.066661 MPa.
Common Use Cases
-
Translating clinical blood pressure readings (mmHg) into engineering pressure units.
-
Interpreting laboratory vapor and partial pressure measurements in terms of mechanical stress.
-
Converting pressure values for material strength specification and hydraulic system design.
-
Relating environmental or physiological pressure data with structural engineering pressures.
Tips & Best Practices
-
Ensure input pressure values correspond to measurements taken at 0°C standard conditions for accuracy.
-
Use the converted MPa values in contexts where high-pressure quantification is necessary.
-
Be aware of the unit differences: mmHg represents relatively low pressures compared to MPa.
-
Double-check for any temperature or gravity deviations that may affect mmHg readings.
Limitations
-
Millimeter mercury is sensitive to temperature and gravity conditions, which may influence conversion precision.
-
Conversions often involve very small decimal values due to the difference in pressure scale.
-
This tool does not adjust for deviations from standard temperature (0°C) or gravity.
Frequently Asked Questions
-
What is millimeter mercury (0°C) used for?
-
Millimeter mercury (0°C) is commonly employed in clinical blood pressure measurements, laboratory manometry, and reporting of vapor and barometric pressures.
-
Why convert millimeter mercury to megapascal?
-
Converting millimeter mercury to megapascal helps translate physiological or laboratory pressures into engineering units for material strength and system design.
-
Does temperature affect the conversion accuracy?
-
Yes, because millimeter mercury is defined at 0°C and standard gravity, variations in these can impact measurement accuracy and conversion results.
Key Terminology

A pressure unit equal to the pressure exerted by a 1 mm column of mercury at 0 °C under standard gravity.
-
Megapascal (MPa)
-
A pressure unit representing one million pascals, used to quantify pressure, mechanical stress, and material strength.
-
Pascal (Pa)
-
The SI unit of pressure equal to one newton per square meter.
