What does millimeter mercury (0°C) measure?

It measures pressure as the force exerted by a 1 mm column of mercury at 0 °C under standard gravity.

Why convert mmHg to millibar?

Converting allows consistent use of pressure units across healthcare, meteorology, and engineering by expressing pressures in commonly used atmospheric units.

Is the millibar the same as hectopascal?

Yes, 1 millibar is numerically equal to 1 hectopascal and both are widely used in meteorology.
