Question

Define pressure. What are the units of pressure in this list:
N/cm², N, N/m², cm², m²

Answer 1

Pressure is the perpendicular force acting per unit area.

Units of pressure:

$$\begin{gathered} \mathrm{Pressure}=\frac{\mathrm{Force}}{\mathrm{Area}} \\ \mathrm{Units}\mathrm{of}\mathrm{Pressure}=\frac{\mathrm{N}}{{\mathrm{m}}^2}\mathrm{and}\frac{\mathrm{N}}{{\mathrm{cm}}^2} \end{gathered}$$
