Formula: Millibar = Kilopascal × 10
Multiply any kilopascal value by 10 to get millibar.
Reverse: Kilopascal = Millibar × 0.1
Common kilopascal values — factor: 1 kPa = 10 mbar

The kilopascal (kPa) equals 1,000 pascals and is the practical everyday pressure unit in metric countries. It is the standard unit for tire pressure, blood pressure, and weather maps in countries using SI.
Blood pressure in many countries is expressed in kPa (normal: ~16/10.7 kPa), though mmHg remains dominant in medicine. Car tire pressure is typically 200–250 kPa. Weather maps use hPa (= mbar) for atmospheric pressure.
Interesting fact: The 'bends' (decompression sickness) in scuba diving occurs when dissolved nitrogen forms bubbles as pressure drops — a drop of just a few kPa too quickly can be fatal.
The millibar (mbar) equals 0.001 bar or 100 pascals, and is numerically identical to the hectopascal (hPa). It became the standard unit for surface pressure in international meteorology in the 20th century.
Weather maps and forecasts worldwide use millibars or hectopascals for surface pressure. Standard sea-level pressure is 1013.25 mbar. Hurricanes and typhoons are characterized by very low central pressures — Hurricane Patricia (2015) reached 872 mbar.
Interesting fact: A 1 mbar pressure difference over 111 km (1° latitude) drives a wind of approximately 1 m/s in mid-latitudes, which is why steep pressure gradients produce strong winds.
Converting kilopascal to millibar is a common task in engineering, medicine, meteorology, and science. Different industries and countries use different pressure units — PSI in the US, bar in Europe, mmHg in medicine, and pascals in physics — making accurate conversion essential for cross-disciplinary work.
Quick reference: 5 kPa = 50 mbar and 10 kPa = 100 mbar. For the reverse: 1 mbar = 0.1 kPa. The exact factor is 1 kPa = 10 mbar.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
