The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m 2, or kg·m −1 ·s −2). This name for the unit was added in 1971; [6] before that, pressure in SI was expressed in newtons per square metre. Other units of pressure, such as pounds per square inch (lbf/in 2) and bar, are also in common use.

8 sie 2022 · The pascal \(\left( \text{Pa} \right)\) is the standard unit of pressure. A pascal is a very small amount of pressure, so the most useful unit for everyday gas pressures is the kilopascal \(\left( \text{kPa} \right)\).
Units of pressure. As stated earlier, the SI unit for pressure is the pascal (Pa), where \[1\; Pa = 1\; N/m^{2} \ldotp\] In addition to the pascal, many other units for pressure are in common use (Table \(\PageIndex{1}\)). In meteorology, atmospheric pressure is often described in the unit of millibars (mb), where
Pressure is force per unit area of surface; the SI unit for pressure is the pascal (Pa), defined as 1 newton per square meter (N/m 2). The pressure exerted by an object is proportional to the force it exerts and inversely proportional to the area on which the force is exerted.
