How do you measure SI pressure?

Answer by  kent16 (178)

If you mean what are the units of SI pressure, they are force per unit area where force is typically in dynes, pascals or kilograms force and area is in square millimeters, square centimeters or square meters. There is also a standard metric atmosphere of pressure

Depends on the application. The standard unit is the Pascal (Pa). 1 Pa is equal to 1KG/(m*s^2), or one newton per square meter. Other units sometimes called "metric" have included the millibar (or bar), Kg/cm^2, or atmospheres (atm). Bars and Pascals have an interesting relationship, 1 hectopascal is equal to 1 millibar.
