About Bar (bar)
A metric unit of pressure equal to exactly 100,000 pascals (100 kPa), approximately the average sea-level atmospheric pressure on Earth (1 atm = 1.01325 bar). Defined by IUPAC and accepted for use with the SI by the BIPM, the bar is not itself an SI-proper unit but is universally recognized in engineering. Bars are the default unit in European industry for compressed gas systems (compressed air at 6-10 bar shop pressure), hydraulics (mobile equipment at 200-400 bar working pressure), and chemical process plants. Car tire pressures in much of the world outside the US are specified in bar (a typical passenger car runs ~2.2 bar / 32 psi cold). Gauges on scuba cylinders (200 bar fill / ~2900 psi), brewery CO₂ tanks, fire suppression systems, and espresso machines (9 bar extraction pressure) all read in bar. 1 bar = 14.504 psi = 100 kPa = 0.9869 atm.
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 Although superseded by SI-proper units (pascal, megapascal) under ISO 80000-4, kgf/cm² persists on industrial gauges in Japan, Korea, and parts of Eastern Europe; on older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.
