A millibar is a pressure unit equal to one-thousandth of a bar, defined as 100 pascals. It is widely used in meteorology to express air pressure.

What does millimeter mercury (0°C) measure?

Millimeter mercury (0°C) measures pressure based on the pressure exerted by a 1 mm column of mercury at 0 °C under standard gravity. It is commonly used in clinical and laboratory settings.

Why should I convert mbar to mmHg?

Converting millibar to millimeter mercury helps translate atmospheric pressure readings into units used in medical blood pressure readings and laboratory measurements.

Is this conversion affected by temperature changes?

Yes, the conversion assumes standard gravity and 0 °C temperature, so variations can slightly affect the mmHg values.
