Millibars to Hectopascals Conversion

Converting Millibars (mbar) to Hectopascals (hPa) is a common pressure conversion. 1 mbar equals 1 hPa. For example, 100 mbar is equal to 100 hPa.

Quick Reference Values

1 mbar = 1 hPa. 5 mbar = 5 hPa. 10 mbar = 10 hPa. 25 mbar = 25 hPa. 50 mbar = 50 hPa. 100 mbar = 100 hPa.

What is Millibars?

Millibars (mbar) is a unit of pressure. The millibar is a unit of pressure equal to 100 pascals or 0.1 kilopascals. It is one-thousandth of a bar, which is defined as exactly 100,000 pascals in the International System of Units (SI). The millibar is commonly used in meteorology to measure atmospheric pressure and is recognized under ISO standards for pressure units [iso-80000]. The bar and its subunit, the millibar, were introduced by the German meteorologist Heinrich von Helmholtz in the early 20th century. The millibar was adopted as a practical unit for meteorological pressure measurements before SI units were formalized [nist-sp-811]. Millibars remain widely used in weather reports and aviation worldwide, especially in countries like the United States, United Kingdom, and Australia. Meteorological agencies, including NOAA and the UK Met Office, use millibars alongside pascals for atmospheric pressure [nist-sp-811].

What is Hectopascals?

Hectopascals (hPa) is a unit of pressure. The hectopascal is a unit of pressure equal to 100 pascals. It is defined as exactly 100 newtons per square meter (100 N/m²), where the pascal (Pa) is the SI derived unit of pressure. The hectopascal is widely used in meteorology for atmospheric pressure measurements and aligns with the SI system as per international standards [bipm-si-brochure]. The pascal unit was named after Blaise Pascal and officially adopted by the General Conference on Weights and Measures (CGPM) in 1971. The hectopascal emerged as a convenient multiple used in meteorology to represent atmospheric pressure values in the 20th century [cgpm-resolutions]. Hectopascals are standard in weather reports worldwide, especially in Europe, Asia, and Australia. The US National Weather Service uses millibars, numerically equivalent to hectopascals, for atmospheric pressure. It is recognized by ISO 80000 as a unit of pressure [iso-80000].

Common Misspellings

People often search for this conversion using these alternate spellings: milibars, milibars, millibar, milibar, hecto pascals, hecto-pascals, hecto pascal, hec topascal. All of these refer to the Millibars to Hectopascals conversion.
