Convert Millipascals to Kilobars
Convert Millipascals (mPa) to Kilobars (kbar) instantly and accurately.
Conversion Formula
kbar = mPa × 1.000000000e-11
About Millipascals
A millipascal (mPa) is 10⁻³ Pa. It appears primarily in rheology as the millipascal-second (mPa·s = centipoise) for dynamic viscosity: water at 20°C is 1.002 mPa·s; olive oil ~80 mPa·s; honey 2,000-10,000 mPa·s. Food technology, polymer processing, pharmaceutical formulation, and inkjet printing all specify flow behaviour in mPa·s. Partial pressures of trace atmospheric gases and ultra-high-vacuum leak rates measured by residual gas analysers are also expressed in millipascals. 1 mPa = 10⁻³ 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.
