About Of
Definition: Millimeter of mercury (symbol: mmHg) measures pressure by the height of mercury column it can support.
History: Based on Torricelli's mercury barometer invented in 1643. Traditional pressure measurement using mercury's density.
Current Use: Medical standard for blood pressure, respiratory medicine, and some scientific applications.
Examples: Blood pressure: 80-120 mmHg, central venous: 2-8 mmHg, intracranial: 5-15 mmHg, altitude: 760 mmHg at sea level
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
