About Bar
Definition: The bar is a metric unit of pressure equal to 100,000 pascals, approximately equal to atmospheric pressure.
History: Introduced in 1909 from Greek "baros" (weight). Widely adopted for its convenient magnitude relative to atmospheric pressure.
Current Use: Common in meteorology, engineering, diving, and industrial applications. Standard for European pressure measurements.
Examples: Weather systems: 0.98-1.05 bar, tire pressure: 2-3 bar, scuba tanks: 200-300 bar, steam systems: 1-20 bar
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
