Understanding Pressure Units

What is a Bar?

A bar is a metric unit of pressure equal to 100,000 pascals (Pa) or approximately 0.987 standard atmospheres. It's commonly used in meteorology and engineering applications.

What is a Millibar?

A millibar (mbar) is equal to one-thousandth of a bar. It's frequently used in weather forecasting and is equivalent to one hectopascal (hPa). Standard atmospheric pressure at sea level is approximately 1,013.25 millibars.
