Origin of 'millibar'
Main points about word origin
- The term 'millibar' comes from 'milli', meaning one-thousandth, and 'bar', derived from Greek, meaning weight.
- It was first introduced in the early 20th century as meteorologists needed a more precise way to measure atmospheric pressure.
The term millibar originated in the early 20th century as a convenient unit of pressure measurement. It was introduced as part of the metric system and has since become widely used in meteorology and other scientific fields. The millibar is derived from the bar, which itself is named after the Greek word 'baros' meaning weight or pressure. Over the years, the millibar has become a standard unit of pressure measurement, particularly in weather forecasting and aviation.
