Pascal (Pa) is a **scalar** quantity. It is the SI unit of pressure, defined as **one newton per square meter (N/m²)**.
Since pressure is defined as force per unit area and acts **equally in all directions** at a point in a fluid, it has **magnitude but no specific direction**. This makes it a **scalar** quantity rather than a vector.
However, while pressure itself is scalar, the **force due to pressure on a surface** is a vector because it acts **perpendicular** to the surface.
