What is 1 "millibar"

Millibar (abbreviated as mbar or mb) is11000 bar, which is the physical unit for measuring pressure. 1 millibar equals 1 hectopascals.

The concept of millibar was invented by Mr. Napier Shaw in 1909, and was internationally recognized in 1929.

Unicode symbol is "mb": (? 9? 6).

Millibar is not an SI unit. The international unit is Pascal (Pa),1mbar =100pa =1HPA = 0.1kpa. Nevertheless, millibar is still a common unit in many occasions.

For a long time, meteorologists all over the world have regarded millibar as one of many units for measuring the atmosphere. It will take some time for Sl unit Pa to be widely adopted. Millibar is still widely used now, although officials of various countries gradually transition to the same numbered Sl unit: hPa. However, hectopascals are usually used instead of hectopascals, because hectopascal prefixes are rarely used in other fields. For example, in the weather forecast in Canada, kPa is usually used as the unit.

Today, millibar is usually used to refer to hurricanes or tornadoes, because lower central air pressure means higher wind speed and more power.
