Millibar (mbar)
Definition
A millibar (mbar) is a unit of pressure equal to one thousandth of a bar, or 100 pascals. It is equivalent to one hectopascal (hPa).
History
The millibar was widely adopted in meteorology in the early 20th century for measuring atmospheric pressure. Many weather services have since transitioned to the equivalent hectopascal (hPa), though millibar remains in common use.
Current use
Millibars are used in meteorology for atmospheric pressure readings, aviation altimeter settings, and weather maps. Many weather forecasts and barometers still display pressure in millibars.
Torr
Definition
A torr is a unit of pressure equal to 1/760 of a standard atmosphere, or approximately 133.322 pascals. It is nearly equivalent to one millimeter of mercury (mmHg).
History
The torr was named after Evangelista Torricelli, the Italian physicist who invented the mercury barometer in 1644. It was defined to provide a convenient way to express vacuum and low-pressure measurements.
Current use
Torr is widely used in vacuum science, semiconductor manufacturing, and laboratory settings for measuring low pressures. It remains a standard unit in physics and materials processing.
