About Pound per Square Inch (psi)
An imperial unit of pressure equal to one pound-force applied over one square inch (exactly 6,894.757 Pa per NIST SP 811). PSI is the dominant US pressure unit and remains the working unit in most US-built industrial, automotive, and consumer equipment: passenger-car tire inflation (32-35 psi cold), compressed air shop systems (typically 100-150 psi), hydraulic equipment (1,500-3,000 psi mobile, up to 10,000 psi on press brakes), ammunition chamber pressures (SAAMI specs in psi), municipal potable water supply (~40-80 psi at the meter), and natural gas distribution pressures. US engineering textbooks and the ASME B31 pipe codes, API piping specifications, and AWWA waterworks standards quote allowable pressures in psi. Engineers should distinguish gauge psi (psig — pressure above atmospheric) from absolute psi (psia — pressure above perfect vacuum); 0 psig = 14.696 psia at sea level. 1 psi = 6.895 kPa = 0.0689 bar = 51.715 mmHg.
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 Although superseded by SI-proper units (pascal, megapascal) under ISO 80000-4, kgf/cm² persists on industrial gauges in Japan, Korea, and parts of Eastern Europe; on older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.
