About Atmosphere
Definition: The atmosphere (symbol: atm) is a unit equal to 101,325 pascals, representing standard atmospheric pressure at sea level.
History: Defined in 1954 as standard reference pressure. Based on average atmospheric pressure at sea level at 15°C.
Current Use: Reference standard for scientific calculations, diving applications, and pressure comparisons.
Examples: Diving: pressure doubles every 10m, chemical reactions: STP conditions, gas laws: standard reference, altitude effects
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
