I kgf/cm2 is equal to________________?
Show answer Hide answer
Answer: C. 735.6 mm Hg
Explanation
Standard conversion factors equate one kilogram-force per square centimeter to millimeter mercury pressure. Hydrostatic pressure calculations link density and height columns to establish this exact equivalence. One kgf/cm2 equals approximately 735.6 millimeters of mercury column height. Pressure units vary across engineering systems, requiring accurate conversion factors for calculations. One atmosphere of pressure is roughly equivalent to 760 mm Hg under standard conditions. Kilogram-force per square centimeter is a traditional metric pressure measurement unit.
Pneumatic and hydraulic equipment specifications often require pressure unit conversions. Laboratory manometer readings in millimeters of mercury correlate directly with engineering pressure scales. Standardizing pressure units prevents catastrophic errors in international industrial projects. Option A defines standard atmospheric pressure rather than one kgf/cm2. Option B represents absolute zero pressure conditions inside a vacuum chamber. Option D and E offer arbitrary pressure values that do not match the correct conversion factor.
