Pronunciation: [mˈɪlɪbˌɑː] (IPA) 
Millibar is spelled with two l's, one i and one b. The word is pronounced /ˈmɪlɪˌbɑr/ in IPA phonetic transcription. The first syllable "mil" is pronounced with a short "i" sound, followed by the "i" in "bar". The "b" in "bar" is pronounced with a soft "b" sound, similar to the "p" in "pot". A millibar is a unit of measurement used to express atmospheric pressure. It is equal to one-thousandth of a bar or 100 pascals.
Millibar is a unit of pressure primarily used in meteorology and atmospheric sciences to measure atmospheric pressure. It is abbreviated as mb and represents one thousandth of a bar, a unit of pressure equal to 100,000 pascals. The millibar scale is commonly used to express changes in atmospheric pressure, especially for weather forecasting purposes.
Atmospheric pressure, also known as air pressure, refers to the force exerted by the weight of the Earth's atmosphere per unit area. It is essential in understanding weather patterns and predicting weather conditions. A millibar, therefore, represents the pressure exerted by the weight of the atmosphere on a specific area and is typically used to describe pressure systems such as high and low-pressure areas, troughs, or ridges.
For reference, the average atmospheric pressure at sea level is around 1013.25 millibars, equivalent to 1 bar or approximately 14.7 pounds per square inch (psi). Lower millibar readings usually indicate the presence of a low-pressure system associated with unstable weather conditions, while higher millibar readings suggest a high-pressure system and generally mean fair and calm weather.
Overall, millibar is an important unit of measurement that helps meteorologists and scientists analyze and predict weather patterns and atmospheric conditions.
A unit of atmospheric pressure, the thousandth part of a bar.

The word "millibar" has its roots in the metric system. It is derived from the combination of two components: "milli-" and "bar".
1. "Milli-" is a prefix in the metric system denoting one-thousandth. It comes from the Latin word "mille", meaning "thousand". This prefix is commonly used to express fractions or multiples of one-thousandth in the metric system.
2. "Bar" refers to a unit of pressure used in meteorology and other sciences. The term "bar" was coined in the late 19th century and comes from the Greek word "baros", meaning "weight" or "pressure".
Therefore, "millibar" can be broken down as "milli-" (one-thousandth) and "bar" (unit of pressure), indicating a pressure measurement equal to one-thousandth of a bar.
