Verified step by step guidance1
Understand that pressure is defined as force applied per unit area.
Recall that the SI unit system uses standard units for all physical quantities, including pressure.
Identify the SI unit for force as the newton (N) and the SI unit for area as the square meter (m\^2).
Use the formula for pressure: \(P = \frac{F}{A}\), where \(P\) is pressure, \(F\) is force, and \(A\) is area.
Recognize that the SI unit for pressure is derived as newtons per square meter, which is called the pascal (Pa).
