 Pascal (unit)

The pascal is the SI unit of pressure:For a uniform normal force of $10\mathrm{N}$ over area $0.02{\mathrm{m}}^2$, the pressure is $500\mathrm{Pa}$. The unit expresses a force per area, rather than the total force alone. ^[ref].

The pascal (symbol: Pa) is the SI unit of pressure, named after the French mathematician and physicist Blaise Pascal. It is defined as one newton per square meter (N/m²). In other words, a pressure of one pascal is produced when a force of one newton is applied uniformly over an area of one square meter. In practical terms, the pascal is often considered a relatively small unit of pressure.
