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 Of
Definition: Inch of mercury (symbol: inHg) measures pressure by the height of mercury column in inches.
History: Imperial equivalent of mmHg, used in countries with imperial measurement systems for barometric readings.
Current Use: Weather reporting in United States, aviation altimeter settings, and some industrial pressure measurements.
Examples: Weather reports: 28-31 inHg, aviation: altimeter settings, barometric trends: ±0.1 inHg/hour, hurricane: <28 inHg
