Answer:
This name for the unit was added in 1971; before that, pressure in SI was expressed simply in newtons per square metre. Other units of pressure, such as pounds per square inch (Ibf/in2) and bar, are also in common use. The CGS unit of pressure is the barye (Ba), equal to 1 dyn. cm−2, or 0.1 Pa.
