Convert Millibars to Kilobars
Convert Millibars (mbar) to Kilobars (kbar) instantly and accurately.
Conversion Formula
kbar = mbar × 1.000000000e-6
About Millibars
A millibar (mbar) = 100 Pa = 1 hPa - the historically dominant meteorological pressure unit. Standard sea-level pressure is 1013.25 mbar. Hurricane intensity is characterised by central pressure: Category 5 storms typically below 920 mbar (US record: 892 mbar, 1935). Upper-air analysis levels - 850, 700, 500, 300, 200 mbar - appear throughout decades of archived meteorological data. Aircraft cabins are pressurised to ~750-800 mbar at cruise altitude. 'Weather bombs' see pressure fall 24+ mbar in 24 hours. 1 mbar = 100 Pa.
About Kilobars
A kilobar (kbar) = 1,000 bar = 100 MPa = 10⁸ Pa - standard in high-pressure geophysics and experimental petrology. Earth mantle phase transitions: olivine → wadsleyite at ~130-140 kbar (410 km depth); post-spinel transition at ~230 kbar (660 km). Diamond anvil cells routinely reach 100-400 kbar for materials synthesis and equation-of-state measurement. High-pressure synthesis of cubic boron nitride (~50 kbar) and superhard materials uses large-volume presses. Explosive shock pressures for mining and demolition: 100-1,000 kbar. 1 kbar = 100 MPa.
