The pascal is the SI derived unit of pressure equal to one newton per square meter.
HistoryThe pascal is named after Blaise Pascal and is the standard SI pressure unit.
Current usePascals are used in science, engineering, materials testing, weather, acoustics, and fluid mechanics.
The standard atmosphere is a pressure unit equal to 101,325 pascals.
HistoryAtmosphere was defined around average sea-level air pressure for reference calculations.
Current useAtmospheres are used in chemistry, gas laws, diving references, and technical pressure comparisons.
