About Gigapascal (GPa)
A metric unit of pressure equal to exactly 1,000,000,000 pascals (1,000 MPa). Gigapascals are the standard unit for reporting elastic-modulus and material-stiffness properties — Young's modulus of structural steel is ~200-210 GPa, aluminum alloys ~69-72 GPa, titanium ~110 GPa, concrete ~25-35 GPa, single-crystal diamond ~1,050-1,200 GPa, and CFRP composite ~150-230 GPa (longitudinal). MatWeb, NIST's MMP database, and the ASM Handbook tabulate elastic constants in GPa. GPa is also the working unit for ultra-high-pressure scientific experiments: diamond-anvil cell measurements (currently extending past 1,000 GPa = 1 TPa for studies of metallic hydrogen and Earth-core conditions), shock-wave equation-of-state research at national labs (LANL, LLNL, Sandia), and geophysics interior models — Earth's outer core lies between roughly 135 and 330 GPa. 1 GPa = 10,000 bar = 145,038 psi.
About Kilogram-force per Square Centimeter (kgf/cm²)
A legacy metric unit of pressure equal to one kilogram-force applied over one square centimeter, formally defined as exactly 98,066.5 Pa (using the standard acceleration of gravity g₀ = 9.80665 m/s² per CIPM Resolution 2, 1901). This is the "technical atmosphere" (symbol at) and is roughly equivalent to one standard atmosphere or one bar — but not exactly. Although superseded by SI-proper units (pascal, megapascal) under ISO 80000-4, kgf/cm² persists on industrial gauges in Japan, Korea, and parts of Eastern Europe; on older industrial machinery; on legacy pressure-vessel drawings (where the implicit assumption of g = 9.80665 m/s² matters); on tire-pressure data tables in some markets; and in older engineering textbooks. Engineers updating legacy documentation should be careful: the technical atmosphere (98,066.5 Pa) is NOT the same as the standard atmosphere (101,325 Pa). Converting kgf/cm² to MPa is divide by 10.197 (a clean approximation: ÷10.2); to psi is multiply by 14.223.
