1 ata of pressure is equivalent to_________________?
Show answer Hide answer
Answer: D. 1 kgf/cm2
Explanation
One atmosphere technical pressure is a traditional metric engineering unit used in industrial pressure measurement. By definition, one ata equals one kilogram force per square centimeter of applied surface area. This unit is frequently utilized in European and older engineering literature for hydraulic calculations. Technical atmosphere differs slightly from standard atmospheric pressure which equals one hundred and one kilopascals. One kilogram force equals the gravitational force exerted on a one kilogram mass under standard gravity. Pressure units help engineers quantify compressive forces acting across industrial vessel and pipe walls.
Industrial pump specifications and hydraulic press designs sometimes reference technical atmospheres in datasheets. Modern international engineering standards prefer SI units like kilopascals and bars over technical atmospheres. Technicians must carefully convert pressure units to avoid catastrophic overpressurization of industrial equipment. One atmosphere represents standard atmospheric pressure which equals one point zero three three technical atmospheres. Ten torr is an extremely low pressure value used in high vacuum system engineering applications. Zero point nine eight Pascal is an insignificantly small pressure value unrelated to technical atmospheres.
