What is Pressure?
Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.
What is Zeptopascal?
The zeptopascal (symbol: zPa) is an SI-derived unit of pressure equal to one sextillionth (10-21) of a pascal. It is used in advanced scientific research, quantum physics, nanotechnology, and ultra-high vacuum studies where extremely small pressure values are encountered. The zeptopascal uses the SI prefix zepto, representing a factor of 10-21.
One zeptopascal is equal to 0.000000000000000000001 pascal, 0.001 attopascal, 1,000 yoctopascals, 1×10-26 bar, and 9.86923×10-27 standard atmosphere. The zeptopascal is an SI unit used for representing extremely low pressure values.
What is Pound Force Per Square Inch?
The pound force per square inch (symbol: psi or lbf/in2) is a non-SI unit of pressure equal to one pound-force applied over an area of one square inch. It is one of the most widely used pressure units in the United States for measuring tire pressure, hydraulic systems, compressed gases, and industrial equipment. Although the pascal is the SI unit of pressure, the psi remains the preferred unit in many engineering applications. More information is available in the pounds per square inch article.
One pound force per square inch is equal to 6,894.76 pascals, 6.89476 kilopascals, 0.0689476 bar, 0.068046 standard atmosphere, and 0.0703069 kilogram-force per square centimetre. The psi is one of the world's most recognized units for measuring pressure.
