Expert Answer:
A dimensionally correct equation might not be correct.
Example -- If we define area of the circle as 2 * radius^2, then it would be dimensionally correct. However, fundamentally the equation is wrong.
On the other hand, the inverse is always true. So, a dimensionally incorrect equation is always wrong as the dimensions on both the sides of equation must match in all circumstances.
So, dimensional correction is a necessary but not sufficient condition for an equation to be correct.
