Question

What is the SI unit of pressure?

Answer 1

Definition of Pressure: Pressure can be defined as the force acting per unit area.

Formula of Pressure: Pressure,$P=\frac{F}{A}$ where, $P$ is pressure, $F$ is force and, $A$ is area.

S.I. unit of Pressure:

$$\begin{gathered} UnitofP=\frac{N}{m^2} \\ UnitofP=N{m}^{-2} \end{gathered}$$

Thus, the S.I. unit of pressure is $N{m}^{-2}$. It is also known as pascal (Pa).
