Si unit of pressure: The pascal (Pa) is

The pascal (Pa) is the SI unit of pressure , defined as one newton per square metre. It is used in various fields such as geophysics, materials science, engineering, and medicine. Discover what is the SI unit of pressure in simple terms. Learn about Pascal (Pa), its real-world applications, and how atmospheric pressure is measured. Learn about the SI unit of pressure , pascal, and other common units of pressure such as bar, atmosphere, torr, and psi. See how to convert between different units of pressure with examples and a conversion table. Pressure Units The SI unit of pressure is the "Pascal (Pa)" , where 1 Pa = 1 N/m 2, i.e. one Newton per square meter. The Newton is the unit of force, so it's easy to see that the Pascal meets the requirements for a unit of pressure . However, the Pascal is quite a small unit for things like atmospheric pressure , so there are quite a large number of alternatives also in use. One of the simplest ways to do this is to simply use kPa (i.e. kilopascals, or thousands of pascals), but there are ...
