🧠 Explanation:

  • The SI unit of pressure is the **Pascal (Pa)**, named after the French mathematician Blaise Pascal.
  • Pressure is defined as **force per unit area**, mathematically: P = F / A.
  • 1 Pascal is equal to 1 Newton per square meter (N/m²).
  • This unit is widely used in physics, meteorology, and engineering to quantify stress, atmospheric pressure, and more.
