Millibar (mbar) to Kilopascals (kPa) 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.
Kilopascals
The kilopascal (kPa) is a unit of pressure equal to exactly 1,000 pascals and is one of the most practical pressure units for everyday engineering. Standard atmospheric pressure is approximately 101.3 kPa. Tyre pressure is commonly specified in kPa in metric countries: a typical car tyre is inflated to 220–250 kPa. Blood pressure in clinical settings is measured in mmHg, but some medical devices express it in kPa (normal systolic ≈ 16 kPa).
