About the pascal
The pascal was named after Blaise Pascal, the 17th-century French mathematician who proved that atmospheric pressure decreases with altitude. It became the SI unit of pressure in 1971.
In everyday use the pascal appears in scientific measurements, material stress analysis, and meteorology. As a point of reference: a sheet of paper resting on a table exerts about 1 pascal of pressure.
