mbar – Millibar Pressure Unit - SensorsONE
Millibar is a metric unit of pressure mainly used in European countries and is derived directly from the bar pressure unit which equals 1,000 mbar. In SI units 1 mbar equals 100 pascals. The millibar is most commonly used to measure barometric pressure for meteorological purposes and low range gas pressures due to its very small value.

The Earth's atmosphere exerts pressure on the surface. Pressure is measured in hectoPascals (hPa), also called millibars. Standard pressure at sea level is defined as 1013hPa, but we can see large areas of either high or low pressure. These areas are all relative to each other, so what defines a high will change depending on the area around it.
