About Pascal
Definition: The pascal (symbol: Pa) is the SI unit of pressure, defined as one newton per square meter of force applied perpendicularly.
History: Named after French mathematician Blaise Pascal in 1971. Adopted as standard SI pressure unit replacing various national standards.
Current Use: Universal scientific and engineering pressure unit. Used in meteorology, materials science, and precise pressure measurements.
Examples: Sound pressure: 20 μPa, blood pressure: 10-20 kPa, vacuum systems: 1-1000 Pa, material stress: MPa range
About Per
Definition: Pound per square inch (symbol: psi) measures pressure as force in pounds applied over one square inch area.
History: Imperial unit developed with pound-force and inch measurements. Standard in United States engineering and industry.
Current Use: Primary pressure unit in United States for tires, hydraulics, pneumatics, and industrial applications.
Examples: Car tires: 30-35 psi, bike tires: 30-100 psi, hydraulic systems: 1000-5000 psi, air compressors: 100-200 psi
