Daniel Bernoulli


Blaise Pascal


Robert Boyle


Archimedes

Detailed explanation1: The pascal (Pa) is the unit of pressure or stress in the International System of Units (SI). It is named after the scientist and mathematician Blaise Pascal. One pascal is equivalent to 1 newton (N) of force applied over an area of 1 square meter (m2).
Detailed explanation2: The unit is named after Blaise Pascal, noted for his contributions to hydrodynamics and hydrostatics, and experiments with a barometer. The name pascal was adopted for the SI unit newton per square metre (N/m2) by the 14th General Conference on Weights and Measures in 1971.
Detailed explanation3: It was named in honour of the French mathematicianphysicist Blaise Pascal (1623–62). A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared.
Detailed explanation4: Other Units of Pascal Multiple units of the pascal are hectopascal, kilopascal and megapascal. Firstly, 1 Hectopascal (hPa) = 100 Pascals (Pa), which is equal to 1 milibar. Furthermore, 1 Kilopascal (kPa) = 1000 Pascals (Pa), which is equal to 1 centibar.
