The Millibar (mbar) in Pressure

What is Millibar (mbar)

The millibar (mbar) is a unit of pressure commonly used in meteorology and atmospheric science. It is defined as one-thousandth of a bar, a unit that is used to measure pressure in various fields, including weather forecasting and engineering. The term "milli" indicates the factor of one-thousandth, so 1 mbar equals 0.001 bar.

One millibar represents the pressure exerted by a 1 mm column of mercury at the standard acceleration due to gravity. It is often used to measure atmospheric pressure, particularly in weather reports where values are typically expressed in hectopascals (hPa), with 1 mbar equaling 1 hPa.

The millibar can also be expressed in various other pressure units, making it versatile for different applications and contexts.
