What is a microbar (µbar)?

A microbar is a pressure unit equal to 10⁻⁶ bar or 0.1 pascal, used to describe very low pressures such as those in vacuum systems or sensitive atmospheric measurements.

Why convert microbar to millimeter mercury (mmHg)?

Converting microbar to millimeter mercury helps express very small pressures in a unit commonly used in clinical, laboratory, and engineering settings for easier interpretation and communication.

Does the conversion account for temperature changes?

The conversion assumes millimeter mercury is defined at 0°C and standard gravity; variations in temperature or gravity may affect the exact equivalency.

Key Features

Converts pressure values from microbar (µbar) to millimeter mercury (mmHg) at 0°C
Based on the standard conversion factor 1 µbar = 0.0007500638 mmHg
Supports interpretations across scientific, clinical, and engineering contexts
Provides quick and accurate unit transformation for low pressure measurements

Examples

Convert 10 microbar to millimeter mercury: 10 × 0.0007500638 = 0.007500638 mmHg
Convert 1000 microbar to millimeter mercury: 1000 × 0.0007500638 = 0.7500638 mmHg

Common Use Cases

Expressing very low pressures from vacuum laboratory systems in mmHg
Converting weak acoustic or infrasound pressure measurements for geophysical monitoring
Reporting clinical blood pressure readings with standard mmHg units
Presenting residual gas pressures in space simulation and spacecraft testing environments
Communicating barometric or moderate vacuum pressures in engineering applications

Tips & Best Practices

Ensure pressure measurements correspond to the conditions assumed for the units (0°C and standard gravity for mmHg)
Use precise instruments when working with very low pressure values due to small decimal conversions
Verify unit labels carefully to avoid confusion between microbar and millimeter mercury
Consider the context of measurement to select appropriate pressure units for communication

Limitations

Conversions result in very small decimal values because microbar measures very low pressures compared to millimeter mercury
Definition of millimeter mercury depends on temperature and gravity constants that may vary in certain conditions
Assumes standard temperature (0°C) and gravity, deviations can affect the equivalency accuracy
