Millibar (mbar) to Pascals (Pa) Conversion
Millibar
The millibar (mbar) is a unit of pressure equal to one thousandth of a bar (100 Pa). It is the standard unit for atmospheric pressure in meteorology: standard atmospheric pressure is 1,013.25 mbar, and weather maps plot isobars (lines of equal pressure) in millibars or hectopascals (1 hPa = 1 mbar). The eye of a powerful hurricane can have a central pressure below 900 mbar, while high-pressure systems typically exceed 1,020 mbar.
Pascals
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²), named after French mathematician Blaise Pascal who studied fluid pressure in the 17th century. Standard atmospheric pressure at sea level is 101,325 Pa (101.3 kPa). The pascal is a small unit for everyday use — a gentle breeze exerts approximately 1 Pa of dynamic pressure — so kilopascals (kPa) and megapascals (MPa) are more common in practical engineering contexts.
