What does one microbar represent?

One microbar is a pressure unit equal to 10⁻⁶ bar, equivalent to 0.1 pascal, used to express very small pressure values.

Why convert from microbar to centimeter mercury (0°C)?

Converting from microbar to centimeter mercury (0°C) enables comparison and calibration in laboratory and engineering contexts where mercury manometers are standard.

Does the conversion factor change with temperature?

Yes, the conversion factor depends on mercury being at 0°C and standard gravity; deviations in these conditions can affect accuracy.
