WebApr 5, 2024 · The pascal (a symbol used is Pa) is the SI derived unit of pressure or stress (also for modulus of elasticity like Young's modulus and tensile strength). The unit of the pressure of the pascal is equivalent to one newton per square metre (N/m2). In our day to day life, the pascal is most frequently used in the form of kilopascal (1 kPa = 1000 Pa). WebMar 16, 2024 · Pressure (of gaseous reactants, for example): Pressure units are derived using the formula Pressure = Force / Area. The SI units for force and area are newtons (N) and square meters (m²), so the SI unit of pressure, the pascal (Pa), can be expressed as N/m². Let’s try an example. A physicist measures the density of a substance to be 20 kg/m³.
