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.
About Technical Atmospheres
One technical atmosphere (at) = exactly 1 kgf/cm² = 98,066.5 Pa ≈ 0.968 standard atmospheres. The metric technical pressure unit used in pre-SI European and Japanese engineering for boilers, hydraulic cylinders, and compressed gas systems. A steam boiler at 10 at operates at 0.981 MPa; hydraulic presses are rated at 200-600 at. Still used parenthetically in old German and Japanese machinery manuals and standards (DIN 1301-3 legacy). Converts simply from kgf/cm²: 1 at ≡ 1 kgf/cm². 1 at = 98,066.5 Pa.
