About Kilopound per Square Inch (ksi)
An imperial unit of pressure equal to exactly 1,000 psi (≈ 6.895 MPa). KSI is the standard US unit for reporting material strength: structural-steel yield (A36 = 36 ksi, A992 W-shapes = 50 ksi, A572-Gr50 plate = 50 ksi, A514 quenched-tempered = 100 ksi), bolt-grade tensile strength (SAE Grade 5 = 120 ksi, Grade 8 = 150 ksi, ASTM A325 = 105-120 ksi, A490 = 150 ksi), aluminum aerospace alloys (7075-T6 ultimate = ~83 ksi), and the S-N fatigue curves in MMPDS / ASME Section VIII Division 3. US structural codes (AISC Steel Construction Manual, AASHTO LRFD Bridge Design), aerospace stress reports, and oil-and-gas casing specifications (API 5CT) all express allowables and yield in ksi. When cross-referencing US alloys against international material databases (typically MPa), the conversion ksi × 6.895 → MPa is essentially universal.
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 Although superseded by SI-proper units (pascal, megapascal) under ISO 80000-4, kgf/cm² persists on industrial gauges in Japan, Korea, and parts of Eastern Europe; on older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.
