About Per
Definition: Pound per square foot (symbol: psf) measures pressure as force in pounds applied over one square foot area.
History: Imperial unit used for distributed loads in construction and engineering applications requiring larger area measurements.
Current Use: Used in United States for building loads, wind pressure, soil pressure, and structural engineering calculations.
Examples: Building loads: 40-100 psf, wind pressure: 10-50 psf, snow loads: 20-80 psf, soil pressure: 1000-4000 psf
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
