Show that $\frac{\text{Joule}}{\text{meter}^2} = \frac{\text{Newton}}{\text{meter}}$.

(N/A) We know that work done or energy is defined as force multiplied by displacement,so $1 \text{ Joule} = 1 \text{ Newton} \times 1 \text{ meter}$.
Substituting this into the expression:
$\frac{\text{Joule}}{\text{meter}^2} = \frac{\text{Newton} \times \text{meter}}{\text{meter}^2}$.
Canceling one meter from the numerator and denominator,we get:
$\frac{\text{Joule}}{\text{meter}^2} = \frac{\text{Newton}}{\text{meter}}$.
