Pascal
Is the unit of pressure in the International System of Units (SI). It also quantifies internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is defined as one newton per square meter, equivalent to 10 baryes (Ba) in the CGS system. The unit of measurement called standard atmosphere (atm) is defined as 101,325 Pa. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar, and the kilopascal (1 kPa = 1000 Pa), which is equal to one centibar [International Bureau of Weights and Measures, p.118].
Unit of pressure and stress in the meter-kilogram-second system (the International System of Units [SI]). It was named in honor of the French mathematician-physicist Blaise Pascal(1623–62). A pascal is a pressure of one newton per square meter, or, in SI base units, one kilogram per meter per second squared. This unit is inconveniently small for many purposes, and the kilopascal(kPa) of 1,000 newtons per square meter is more commonly used. For example, the standard atmospheric pressure (or 1 atm) is 101.325 kPa. The millibar, a unit of air pressure often used in meteorology, is equal to 100 Pa. (For comparison, one pound per square inch equals 6.895 kPa.) [Online Encyclopaedia Britannica].
The derived SI unit of pressure; is the pressure exerted on an area of 1 square meter by a force of 1 newton; equivalent to 10 dynes per square centimeter or 1.45 × 10–4 pounds per square inch [Collins Online Dictionary].
